1.6mm High 10A Power Module with PMBus Interface

March 25, 2019 by Scott McMahan

Monolithic Power has launched, MPM3695A-10, an ultra-thin, scalable and fully integrated power module with PMBus interface. MPM3695A-10 offers a complete power solution that achieves up to 10A of continuous output current with excellent load and line regulation over a voltage range from 3V to 14V. MPM3695A-10's 1.6mm height enables it to be placed on the back-side of a PCB for space optimization. The module operates at high efficiency and can be paralleled to deliver up to 60A of continuous current.

It uses MPS's proprietary, multi-phase constant-on-time (MCOT) control, which delivers ultra-fast transient response and simple loop compensation. The PMBus interface provides module configurations and monitors critical parameters.

MPM3695A-10 features full protection functions including over-current protection, over-voltage protection, under-voltage protection, and over-temperature protection. The power module requires a minimal number of readily available external components and is available in a QFN-45 (8mmx8mmx1.6mm) package.

The device is PMBus 1.3 compliant. Telemetry read-back includes Vin, Vout, Iout, temperature, and faults. It operates in either PWM mode or switching frequency mode.
