Product details
Overview
The MAX15106AGWP+T from Analog Devices is a high-efficiency, current-mode, synchronous step-down switching regulator with integrated 6A power switches, operating from 2.7V to 5.5V input and delivering adjustable output from 0.6V to 95% of VIN. It features factory-trimmed 0.9MHz fixed-frequency PWM operation, ±1% output voltage accuracy over load/line/temperature, and capacitor-programmable soft-start. It is designed for point-of-load regulation in notebook power, DDR memory, and distributed power systems.
For engineers reviewing the MAX15106AGWP+T datasheet, MAX15106AGWP+T pinout, MAX15106AGWP+T application, or MAX15106AGWP+T equivalent, key selection considerations include its 20-bump WLP package (2.5mm × 2mm), cycle-by-cycle overcurrent protection, safe prebiased startup capability, forced PWM mode, and compatibility with all-ceramic output capacitor designs.
Technical Context
The MAX15106AGWP+T implements peak-current-mode control using a high-gain transconductance error amplifier (gMV = 1.4 mS) and a PWM comparator that compares COMP voltage against a composite ramp (current-derived + compensation ramp). Its 0.9MHz fixed switching frequency enables compact external component sizing and supports fast transient response with ceramic-only output filtering.
Internal protection includes cycle-by-cycle high-side current limiting (7.5–12.5A), low-side sink/source current limits, thermal shutdown at +160°C with +25°C hysteresis, input undervoltage lockout (2.6V threshold, 200mV hysteresis), and hiccup-mode overload recovery after eight consecutive current-limit events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | Continuous 6A - supports high-current point-of-load rails without external MOSFETs or heatsinks. |
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion, USB PD, and intermediate bus supplies. |
| Output Voltage Range | 0.6V to 0.95 × VIN - enables precise core voltage regulation for modern processors and memory. |
| Switching Frequency | 0.9MHz (factory-trimmed) - allows use of small inductors and all-ceramic output capacitors. |
| Output Accuracy | ±1% over load, line, and temperature - ensures stable voltage margins for DDR and CPU cores. |
| Soft-Start Control | Capacitor-programmable via SS pin - reduces input inrush current and prevents system brownout during startup. |
| Thermal Protection | Thermal shutdown at +160°C with +25°C hysteresis - prevents permanent damage under sustained overload or poor airflow. |
Pinout & Package
The MAX15106AGWP+T is housed in a 20-bump, 2.5mm × 2mm, 0.5mm pitch Wafer-Level Package (WLP) with exposed thermal pad on underside. The package is RoHS-compliant and rated for -40°C to +105°C ambient operation.
| 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 to solid ground plane for thermal and EMI performance. |
| A2, A3, B2, C2 | LX | Switch node connecting to inductor; carries high di/dt; requires short, low-inductance layout to minimize ringing and EMI. |
| A4 | PGOOD | Open-drain power-good signal asserting low when FB < 530mV; used for supply sequencing and fault monitoring. |
| B3, C3, D3 | IN | Main input power supply (2.7V–5.5V); requires ≥10µF low-ESR ceramic bypass to PGND close to package. |
| B4, C4 | I.C. | Internally connected - leave unconnected and unpopulated on PCB. |
| B5 | FB | Feedback input sensing output voltage divider; reference threshold is 600mV ±6mV across temperature. |
| C5 | SS | Soft-start timing and external reference input; sourcing 10µA current to set startup ramp time or accept external tracking voltage. |
| D2 | INX | Control-section input bump - must be connected to IN for proper biasing of internal circuitry. |
| D4 | EN | Enable input with 1.3V high-threshold; drives high to activate regulator; connect to IN for always-on operation. |
| D5 | COMP | Error amplifier output; connects to RC compensation network to SGND for loop stability and transient response tuning. |
Key Features

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 |
|---|---|---|---|
| TPS546B24RVFT | 4.5–18V input range; 1.5MHz switching; PMBus interface; higher VIN max but larger 24-pin QFN package. | Targets higher-input industrial/military systems; lacks prebiased startup and WLP footprint. | Choose TPS546B24RVFT when input exceeds 5.5V or digital telemetry is required; avoid if board space or low-VIN operation is critical. |
| ISL8206MIRZ | 4.5–14V input; 6A output; 600kHz switching; 15mm × 15mm module with integrated inductor. | Offers full power module simplicity but sacrifices PCB-level optimization and ceramic-cap-only design flexibility. | Choose ISL8206MIRZ for rapid prototyping or where layout expertise is limited; avoid when optimizing for cost, size, or efficiency at light loads. |
Compared with TPS546B24RVFT and ISL8206MIRZ, the MAX15106AGWP+T delivers superior integration density (2.5mm × 2mm WLP), native support for 2.7V inputs, and guaranteed prebiased startup - making it optimal for space-constrained, low-voltage, high-reliability embedded power rails.

FAQ
What is the maximum output current capability of the MAX15106AGWP+T?
The MAX15106AGWP+T delivers continuous 6A output current under specified thermal conditions (TBOARD = +70°C, four-layer board). Its integrated MOSFETs feature low RDS(ON), enabling this rating without external components. Derating applies above +70°C ambient per θJA = 47°C/W; full 6A is maintained up to +105°C case temperature with appropriate PCB copper area.
Does the MAX15106AGWP+T support startup into a prebiased output voltage?
Yes, the MAX15106AGWP+T 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 voltage crosses the FB threshold, preventing reverse current flow. This behavior is confirmed in the device's functional diagram and typical waveforms (Figure toc16/toc17).
What package type and dimensions does the MAX15106AGWP+T use?
The MAX15106AGWP+T uses a 20-bump Wafer-Level Package (WLP) with 2.5mm × 2mm body size and 0.5mm pitch. Its land pattern follows Application Note 1891, and soldering requires JEDEC J-STD-020A reflow profile with preheating - hand or wave soldering is not permitted due to thermal limitations of the WLP construction.
How is the output voltage set on the MAX15106AGWP+T?
The output voltage is set using an external resistive divider from VOUT to FB to PGND. With a feedback reference voltage of 600mV ±6mV, R1 and R2 are selected per VOUT = 0.6V × (1 + R1/R2). Typical R2 values range from 1kΩ to 20kΩ; lower values improve accuracy against FB input bias current (±100nA) but increase divider power loss.
What protection features are integrated into the MAX15106AGWP+T?
The MAX15106AGWP+T integrates cycle-by-cycle overcurrent protection (high-side limit: 7.5–12.5A), thermal shutdown (+160°C with +25°C hysteresis), input undervoltage lockout (2.6V threshold), hiccup-mode overload recovery, and safe prebiased startup. All protections are fully autonomous and require no external components to function.
