Product details
Overview
The MAX15106BGWP+ 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 1.0MHz 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 MAX15106BGWP+ datasheet, MAX15106BGWP+ pinout, MAX15106BGWP+ application, or MAX15106BGWP+ equivalent, this page delivers verified technical context, validated pin functions, confirmed thermal and electrical specifications, and real-world sequencing and soft-start implementation details - all specific to the MAX15106B variant in 20-bump WLP packaging.
Technical Context
This IC implements peak-current-mode control using a 1.4mS transconductance error amplifier and a 25A/V COMP-to-current-sense transconductance, enabling cycle-by-cycle current limiting and fast transient response. The internal 1.0MHz oscillator (MAX15106B) drives forced-PWM operation with 94% maximum duty cycle and 100ns minimum controllable on-time.
It integrates high- and low-side MOSFETs with 7.5A–12.5A high-side current-limit threshold and dual low-side sink/source limits (7A/9A), plus hiccup-mode overcurrent protection triggered after eight consecutive current-limit events. Thermal shutdown activates at +160°C with +25°C hysteresis, and safe startup into prebiased outputs is ensured via SS voltage monitoring and forced-start logic.

Pinout & Package
The MAX15106BGWP+ is housed in a 20-bump, 2.5mm × 2mm, 0.5mm pitch Wafer-Level Package (WLP) with exposed die pad for thermal conduction. This ultra-compact package supports high-density routing and first-pass layout success in mobile and server point-of-load applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A5, B1, C1, D1 | PGND | Power ground return for both input and output capacitors; must connect directly to solid ground plane to minimize noise and ensure current-mode stability. |
| A2, A3, B2, C2 | LX | Switch node connecting to inductor; carries high di/dt current - requires short, wide trace and tight loop area with PGND to reduce EMI. |
| A4 | PGOOD | Open-drain power-good signal asserting low when FB < 530mV; used for supply sequencing with other regulators or system controllers. |
| B3, C3, D3 | IN | Main input power rail (2.7V–5.5V); bypassed with ≥10µF ceramic capacitor to PGND near package for high-frequency decoupling. |
| B4, C4 | I.C. | Internally connected - must remain unconnected and unstubbed to avoid parasitic coupling or impedance mismatch. |
| B5 | FB | Feedback input sensing output voltage divider; 600mV nominal threshold with ±6mV tolerance - sets output precision and loop stability. |
| C5 | SS | Soft-start and external reference input; sourcing 10µA to charge external capacitor - controls startup slew rate and enables tracking mode with external voltage source. |
| D2 | INX | Control-section input bump - tied internally to IN; must be connected to same net as IN for proper biasing of internal logic. |
| D4 | EN | Enable input with 1.3V high-threshold; drives regulator into full operation when pulled high - supports flexible power sequencing and standby control. |
| D5 | COMP | Error amplifier output; connects to RC compensation network between COMP and PGND - determines loop bandwidth and phase margin. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitor-programmable soft-start | 10µA constant-current source into SS pin enables precise control of output ramp time - reduces input inrush and prevents brownout during cold start. |
| Safe prebiased startup | Internal logic holds both HS and LS switches off until SS > FB, preventing reverse current flow into precharged output - eliminates need for external blocking diodes. |
| Forced PWM mode | Guarantees continuous switching regardless of load - avoids subharmonic instability and maintains predictable EMI profile in light-load conditions. |
| Cycle-by-cycle overcurrent protection | Monitors high-side current every switching cycle with 7.5A–12.5A programmable threshold - protects against short circuits and inductor saturation without delay. |
| Stable with low-ESR ceramic capacitors | Eliminates need for electrolytic or tantalum output caps - improves reliability, lifetime, and temperature performance in harsh environments. |

FAQ
What is the switching frequency of the MAX15106BGWP+?
The MAX15106BGWP+ operates at a factory-trimmed fixed switching frequency of 1.0MHz. This value is specific to the MAX15106B variant and is guaranteed across the full –40°C to +105°C operating temperature range. The 1.0MHz frequency enables compact all-ceramic capacitor designs and supports fast transient response without requiring external frequency programming components. Unlike the MAX15106A (0.9MHz) or MAX15106C (1.1MHz), the MAX15106BGWP+ is strictly rated for 1.0MHz operation per its datasheet specifications.
Does the MAX15106BGWP+ support startup into a prebiased output?
Yes, the MAX15106BGWP+ supports safe startup into a prebiased output. Its internal logic monitors the SS pin voltage relative to FB and holds both high-side and low-side switches off until SS exceeds FB, preventing reverse current flow and output capacitor discharge. This capability is confirmed in the Functional Diagram and Detailed Description sections of the datasheet and applies specifically to the MAX15106B variant. No external circuitry is required to enable this feature.
What package type does the MAX15106BGWP+ use, and what are its thermal characteristics?
The MAX15106BGWP+ uses a 20-bump, 2.5mm × 2mm Wafer-Level Package (WLP) with 0.5mm pitch. Its thermal resistance from junction to ambient (θJA) is 47°C/W on a four-layer board. The device includes thermal shutdown at +160°C with +25°C hysteresis, and the WLP construction complies with JEDEC JESD51-7 measurement standards. The package is RoHS-compliant and requires reflow per JEDEC J-STD-020A, paragraph 7.6, Table 3 - hand or wave soldering is not permitted.
How is output voltage set on the MAX15106BGWP+?
Output voltage on the MAX15106BGWP+ is set using an external resistive divider from VOUT to FB to PGND. The feedback threshold is 0.6V (VFB), so R1 and R2 are selected such that VOUT = 0.6V × (1 + R1/R2). Typical R2 values range from 1kΩ to 20kΩ, with 5kΩ commonly used to balance precision and power dissipation. The FB input bias current is ±100nA, which must be considered when selecting resistor values to maintain ±1% output accuracy.
What protection features does the MAX15106BGWP+ include?
The MAX15106BGWP+ includes cycle-by-cycle overcurrent protection (with 7.5A–12.5A high-side current limit), hiccup-mode fault recovery (triggered after eight consecutive current-limit events), input undervoltage lockout (2.7V threshold with 200mV hysteresis), thermal shutdown (+160°C), and safe prebiased startup. All protections are fully integrated and require no external components. These features are validated for the MAX15106B variant and operate across the full –40°C to +105°C temperature range.
