The LP8731-Q1 is a multi-function, programmable Power Management Unit (PMU), optimized for low power FPGAs, microprocessors, and DSPs. This device integrates two highly efficient 1.2-A step-down DC-DC converters with dynamic voltage management (DVM), two 300-mA linear regulators, and a 400-kHz I2C-compatible interface to allow a host controller access to the internal control registers of the LP8731-Q1. The LP8731-Q1 device additionally features programmable power-on sequencing.
