Product details
Overview
MAX15106CGWP+ 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, adjustable output voltage from 0.6V to 95% of VIN, and fixed 1.1MHz PWM switching frequency - ideal for notebook power, DDR memory, and point-of-load regulation in compact portable systems.
For engineers reviewing the MAX15106CGWP+ datasheet, MAX15106CGWP+ pinout, MAX15106CGWP+ application, or MAX15106CGWP+ equivalent, this page delivers verified technical context, validated pin functions, confirmed WLP package mapping, real-world soft-start and prebias behavior, and two rigorously cross-checked alternative regulators for distributed power and embedded DC-DC design.
Technical Context
The MAX15106CGWP+ implements peak-current-mode control using a 1.4mS transconductance error amplifier and a 25A/V COMP-to-current-sense transconductance, enabling stable loop compensation with ceramic-only output capacitors. Its fixed 1.1MHz oscillator (MAX15106C variant) supports sub-2mm² layout with minimal external components.
It integrates high-side and low-side MOSFETs with 7.5A–12.5A programmable high-side current limit and 7A/9A low-side sink/source limits, plus cycle-by-cycle overcurrent protection, thermal shutdown at +160°C, and safe startup into prebiased outputs without discharging the output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | Continuous 6A - supports full-load operation in DDR memory rails and notebook core supplies without external heatsinking. |
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion, USB PD, and intermediate bus voltages in portable and server applications. |
| Switching Frequency | 1.1MHz (factory-trimmed) - enables use of small 0.47µH–1.0µH inductors and all-ceramic 22µF–100µF output capacitors. |
| Feedback Accuracy | ±1% over line, load, and temperature - ensures tight regulation for sensitive SoC and FPGA core voltages. |
| Soft-Start Control | Capacitor-programmable (ISS = 10µA) - reduces input inrush current during power-up; supports external tracking reference on SS pin. |
| Thermal Protection | Thermal shutdown at +160°C with +25°C hysteresis - prevents permanent damage under sustained overload or poor airflow conditions. |
| Power-Good Threshold | 0.555V rising / 0.53V falling (25mV hysteresis) - provides reliable sequencing signal for multi-rail systems with ±2% tolerance. |
Pinout & Package
MAX15106CGWP+ is housed in a 20-bump, 2.5mm × 2mm, 0.5mm pitch Wafer-Level Package (WLP), optimized for ultra-compact PCB layouts and thermal performance on four-layer boards (θJA = 47°C/W).
| 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 PGND plane for EMI and thermal integrity. |
| A2, A3, B2, C2 | LX | Switch-node connection to inductor; carries full AC ripple current and requires short, wide copper pour to minimize ringing and losses. |
| A4 | PGOOD | Open-drain power-good output; asserts low when FB falls below 0.53V - used for system-level power sequencing and fault reporting. |
| 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 trace or pad allowed. |
| B5 | FB | Feedback input for output voltage regulation; connects to center tap of resistive divider (R1/R2) setting VOUT = 0.6V × (1 + R1/R2). |
| C5 | SS | Soft-start and external reference input; sinking 10µA current to set startup ramp time; accepts external 0V–(VIN − 1.5V) tracking voltage. |
| D2 | INX | Control-section input bump - must be tied directly to IN; not a separate supply rail. |
| D4 | EN | Enable input; logic-high (>1.3V) activates regulator; tie to IN for always-on operation; <0.4V disables converter with <3µA shutdown current. |
| D5 | COMP | Error amplifier output; connects to RC compensation network (to PGND) - critical for stability; clamp low at 0.93V aids transient recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6A Power Stage | Low RDS(ON) high-side/low-side MOSFETs eliminate external FETs and drivers - reduces BOM count and layout complexity for space-constrained designs. |
| Prebias-Safe Startup | Starts into precharged outputs (e.g., hot-plug or rail-sharing scenarios) without discharging the output capacitor - avoids system reset or brownout. |
| Forced PWM Mode | Maintains constant switching frequency across all loads - eliminates audible noise and ensures predictable EMI profile in battery-powered devices. |
| Hiccup Overcurrent Recovery | After eight consecutive current-limit events, enters 1024-clock-cycle hiccup mode - protects against sustained short circuits while enabling automatic recovery. |
| Input UVLO with Hysteresis | Turns on at VIN ≥ 2.7V (typ), turns off at VIN ≤ 2.5V - prevents erratic operation during brownout or weak battery conditions. |
Applications
| DDR Memory Power | Notebook Core Supply |
|---|---|
Use Scenario: Providing tightly regulated 1.2V/1.35V/1.5V VDDQ or VDDIO rails for DDR4/DDR5 memory subsystems in ultrabooks and edge servers. IC Role / Device Role / Timing Role: Primary synchronous buck regulator delivering continuous 6A with ±1% accuracy and fast load-transient response (<50µs settling). Use Value: Maintains memory timing margins under dynamic burst loads; eliminates need for external LDO post-regulation due to inherent accuracy and low output impedance. |

Use Scenario: Local regulation of 1.8V or 2.5V auxiliary rails from 5V backplane in industrial PLCs and telecom line cards. IC Role / Device Role / Timing Role: Compact, thermally robust POL regulator supporting -40°C to +105°C ambient operation with full 6A capability. Use Value: Eliminates discrete controller + external MOSFET solution; WLP thermal resistance (θJA = 47°C/W) sustains full load without derating in convection-cooled enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2451DT-LF-Z | 3A rated, 2MHz fixed frequency, 4.5V–28V input - lacks prebias startup, lower current, wider VIN range. | Suitable for higher-input industrial rails but cannot replace MAX15106CGWP+ in 6A DDR or notebook core applications. | Select only if input exceeds 5.5V or 3A output suffices; verify soft-start and sequencing compatibility. |
| TPS546B24RVFT | 6A, 1.5V–16V input, PMBus interface, 500kHz–2MHz programmable frequency - larger QFN package, digital control overhead. | Used where telemetry, margining, or dynamic voltage scaling is required; overkill for fixed-output, analog-controlled systems. | Choose only when digital monitoring or adaptive frequency tuning is mandatory; adds firmware and layout complexity. |
Compared with MP2451DT-LF-Z and TPS546B24RVFT, the MAX15106CGWP+ uniquely combines 6A analog current-mode control, 1.1MHz fixed frequency, prebias-safe startup, and 2.5mm × 2mm WLP in a production-validated single-chip solution - making it optimal for space- and efficiency-critical portable and memory power designs where simplicity and reliability are prioritized over configurability.

FAQ
What is the switching frequency of the MAX15106CGWP+?
The MAX15106CGWP+ operates at a factory-trimmed fixed switching frequency of 1.1MHz. This value is specific to the MAX15106C variant and is guaranteed across temperature and input voltage (850kHz to 1250kHz min/max). It enables compact magnetics and all-ceramic output filtering without requiring frequency synchronization circuitry. The MAX15106CGWP+ does not support external frequency programming or spread-spectrum modulation.
Does the MAX15106CGWP+ support startup into a prebiased output?
Yes, the MAX15106CGWP+ safely starts into a prebiased output without discharging the output capacitor. During prebias startup, both high-side and low-side MOSFETs remain off until the SS pin voltage crosses the FB threshold (~0.58V), preventing reverse current flow. This behavior is confirmed in the datasheet's "Starting into a Prebiased Output" section and validated in typical waveforms (toc16/toc17). The MAX15106CGWP+ maintains this capability across its full -40°C to +105°C operating range.
What package type and dimensions does the MAX15106CGWP+ use?
The MAX15106CGWP+ uses a 20-bump Wafer-Level Package (WLP) with 2.5mm × 2mm footprint and 0.5mm bump pitch. Its package code is W202D2Z+1, outline number 21-0505. The WLP construction requires JEDEC J-STD-020A-compliant reflow profiles with preheating; hand soldering and wave soldering are prohibited. Thermal resistance is θJA = 47°C/W on a four-layer board.
How is output voltage set on the MAX15106CGWP+?
Output voltage is set via an external resistive divider from VOUT to FB to PGND. The internal feedback reference is 0.6V (±1% over temperature), so VOUT = 0.6V × (1 + R1/R2). Recommended R2 values range from 1kΩ to 20kΩ (5kΩ typical) to balance bias current error and power dissipation. The MAX15106CGWP+ does not support resistor-programmable or digital VOUT setting - adjustment is strictly analog through the FB divider network.
What protection features are integrated into the MAX15106CGWP+?
The MAX15106CGWP+ integrates cycle-by-cycle overcurrent protection (high-side limit: 7.5A–12.5A; low-side sink/source: 7A/9A), thermal shutdown at +160°C with +25°C hysteresis, input undervoltage lockout (2.7V turn-on, 200mV hysteresis), hiccup-mode recovery after eight current-limit events, and safe prebias startup. All protections are hardware-based with no software dependency, ensuring fail-safe operation under fault conditions across its full temperature range.
