Product details
Overview
The MAX15106AGWP+ from Analog Devices is a high-efficiency, current-mode, synchronous step-down switching regulator with integrated power switches, delivering up to 6A output current from a 2.7V–5.5V input and supporting adjustable output voltages from 0.6V to 95% of VIN. It features factory-trimmed 0.9MHz fixed-frequency PWM operation, ±1% FB set-point accuracy over load/line/temperature, and operates across –40°C to +105°C - ideal for notebook power, DDR memory, and distributed point-of-load systems.
For engineers reviewing the MAX15106AGWP+ datasheet, MAX15106AGWP+ pinout, MAX15106AGWP+ application, or MAX15106AGWP+ equivalent, this page delivers verified technical context, validated pin functions, confirmed ceramic-capacitor compatibility, real-world soft-start behavior into prebiased outputs, and precise alternative selection guidance for 6A buck regulator designs.
Technical Context
The MAX15106AGWP+ implements peak-current-mode control using a 1.4mS transconductance error amplifier and a 25A/V COMP-to-current-sense transconductance stage, enabling cycle-by-cycle current limiting and fast transient response. Its fixed 0.9MHz oscillator ensures stable all-ceramic capacitor design with minimal external component count.
Internal protection includes hiccup-mode overcurrent (triggered after eight consecutive high-side current-limit events), thermal shutdown at +160°C with +25°C hysteresis, input undervoltage lockout (2.7V threshold, 200mV hysteresis), and safe startup into prebiased outputs via SS voltage monitoring and forced PWM initiation at 0.58V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | Continuous 6A - supports full-load operation without derating in typical PCB layouts with four-layer board thermal management. |
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion, USB PD, and intermediate bus rails in portable and embedded systems. |
| Output Voltage Range | 0.6V to 0.95 × VIN - enables direct regulation of DDR VDDQ (1.2V), core logic (0.9V), and I/O supplies without external LDO post-regulation. |
| Switching Frequency | 0.9MHz (factory-trimmed) - allows use of ≤1µH inductors and all-ceramic output capacitors while maintaining >90% efficiency at 6A. |
| FB Accuracy | ±1% over load, line, and temperature - ensures tight output regulation across industrial temperature range without calibration. |
| Efficiency | Up to 96% - achieved via low RDS(ON) integrated MOSFETs and optimized gate drive, reducing thermal stress in compact layouts. |
| Soft-Start Control | Capacitor-programmable (ISS = 10µA) - enables controlled ramp-up to limit input inrush current during cold start or hot-plug events. |
| Thermal Protection | 160°C shutdown with 25°C hysteresis - prevents permanent damage during sustained overload or poor airflow conditions. |
Pinout & Package
The MAX15106AGWP+ is housed in a 20-bump, 2.5mm × 2mm WLP package with 0.5mm pitch and bottom-side solder bumps. This ultra-compact wafer-level package supports high-density PCB layouts and requires JEDEC JESD22-A113-compliant reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A5, B1, C1, D1 | PGND | Power ground return for both high-side and low-side switches - must connect directly to solid internal PGND plane to minimize noise and ensure current-limit accuracy. |
| A2, A3, B2, C2 | LX | Switch-node connection to inductor - carries high di/dt ripple current; requires short, wide copper trace to reduce EMI and voltage overshoot. |
| A4 | PGOOD | Open-drain power-good signal - asserts low when FB falls below 530mV; used for sequencing with downstream regulators or system controllers. |
| B3, C3, D3 | IN | Main input supply (2.7V–5.5V) - requires ≥10µF low-ESR ceramic bypass capacitor placed adjacent to IN and PGND pins. |
| B4, C4 | I.C. | Internally connected - must remain unconnected on PCB; no external circuitry allowed. |
| B5 | FB | Feedback input referenced to 0.6V internal reference - connects to resistor divider from output to PGND to set regulated voltage. |
| C5 | SS | Soft-start timing and external reference input - capacitor to PGND sets startup time; external voltage (0V to VIN–1.5V) enables tracking applications. |
| D2 | INX | Control-section input bump - internally tied to IN; must be connected to same net as IN for proper biasing. |
| D4 | EN | Enable input - logic-high (>1.3V) enables regulation; tie to IN for always-on operation; supports power sequencing with external controllers. |
| D5 | COMP | Error amplifier output - connects to RC compensation network (to PGND) to stabilize feedback loop; clamp low at 0.93V aids transient recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Current-mode control architecture | Enables stable all-ceramic capacitor designs and simplifies compensation with predictable pole-zero placement for first-pass layout success. |
| Capacitor-programmable soft-start | Reduces input inrush current by controlling dVOUT/dt; supports safe startup into prebiased outputs without discharging existing rail voltage. |
| Integrated 6A synchronous power switches | Eliminates external MOSFETs and drivers, reducing BOM count and layout complexity while maintaining >95% efficiency at full load. |
| Forced PWM mode | Ensures continuous switching under light loads - avoids frequency modulation artifacts and maintains consistent EMI profile across load range. |
| Prebias-safe startup logic | Monitors SS and FB to delay PWM activation until SS exceeds FB, preventing reverse current flow through internal body diodes during hot-insertion. |
| Hiccup-mode overcurrent protection | Enters 1024-clock-cycle recovery timeout after eight consecutive current-limit events - protects against sustained short-circuit faults without latch-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS546B24RVFT | 6A, 1.2MHz, 2.95–16V input, integrated FETs, PMBus interface - wider VIN range but larger 4mm × 4mm QFN package. | Supports telemetry and dynamic voltage scaling via PMBus; suited for server VR13/VR14 compliance where digital control is required. | Select TPS546B24RVFT when digital monitoring, margining, or adaptive loop tuning is needed - not drop-in due to different pinout and control interface. |
| MP2315GJ-Z | 6A, 1.1MHz, 4.5–28V input, 0.8V reference, smaller 3mm × 3mm QFN - lacks prebias-safe startup and hiccup-mode protection. | Targeted at industrial motor drives and PoE-powered devices where higher VIN and cost sensitivity outweigh advanced safety features. | Select MP2315GJ-Z for cost-driven, high-VIN applications where soft-start into prebiased rails and hiccup recovery are not required. |
Compared with TPS546B24RVFT and MP2315GJ-Z, the MAX15106AGWP+ offers superior thermal performance in ultra-compact WLP form factor, guaranteed prebias-safe startup, and deterministic hiccup-mode fault handling - making it optimal for space-constrained, reliability-critical portable and telecom applications.

FAQ
What is the switching frequency of the MAX15106AGWP+?
The MAX15106AGWP+ operates at a factory-trimmed fixed switching frequency of 0.9MHz. This value is specified in the Electrical Characteristics table under "Oscillator" and is guaranteed across the full –40°C to +105°C operating temperature range. The 0.9MHz frequency enables compact magnetics and all-ceramic capacitor designs while maintaining high efficiency at 6A output current. The MAX15106AGWP+ variant is part of the A-grade version, distinct from the 1.0MHz (B) and 1.1MHz (C) variants in the same family.
Does the MAX15106AGWP+ support startup into a prebiased output?
Yes, the MAX15106AGWP+ safely starts into a prebiased output without discharging the output capacitor. Its internal logic monitors the SS and FB pins and delays PWM activation until SS exceeds FB, preventing reverse current flow through internal MOSFET body diodes. This behavior is confirmed in the "Starting into a Prebiased Output" section of the datasheet and validated by typical waveforms (toc16 and toc17). The MAX15106AGWP+ also includes low-side sink current limiting (1A) to protect against excessive reverse current during prebias conditions.
What package type does the MAX15106AGWP+ use?
The MAX15106AGWP+ uses a 20-bump wafer-level package (WLP) measuring 2.5mm × 2mm with 0.5mm pitch. This is explicitly stated in the "Package Information" section and confirmed by the land pattern number (AN1891) and outline number (21-0505). The WLP construction requires JEDEC JESD22-A113-compliant reflow profiles and prohibits hand or wave soldering. The "+" suffix in the part number denotes RoHS-compliant finish per Analog Devices' packaging conventions.
What is the FB reference voltage for the MAX15106AGWP+?
The MAX15106AGWP+ has a nominal FB reference voltage of 0.600V, with guaranteed limits of 0.594V to 0.606V over load, line, and temperature. This ±1% accuracy is specified in the "Electrical Characteristics" table under "FB Set-Point Accuracy" and is critical for achieving tight output voltage regulation. The reference is internally trimmed and does not require external calibration. When setting output voltage using an R1/R2 divider, the formula VOUT = 0.6 × (1 + R1/R2) applies directly.
How does overcurrent protection work in the MAX15106AGWP+?
The MAX15106AGWP+ employs cycle-by-cycle overcurrent protection with hiccup-mode recovery. Each high-side switch current-limit event (typ. 9A) triggers immediate turn-off; a 3-bit counter increments on each event. After eight consecutive events without recovery, the device discharges SS, halts switching, and waits 1024 clock cycles before attempting soft-start again. This behavior is documented in the "Overcurrent Protection and Hiccup" section and verified by oscilloscope waveform toc12. Unlike latch-off protection, hiccup mode enables automatic recovery after fault removal.
