Texas Instruments LP3907SQ-BFX6W/NOPB

Description
The LP3907 is a multi-function, programmable Power Management Unit, optimized for low power FPGAs, microprocessors, and DSPs. This device integrates two highly efficient 1-A/600-mA step-down DC-DC converters with dynamic voltage management (DVM), two 300-mA linear regulators, and a 400-kHz I2C interface to allow a host controller access to the internal control registers of the device. The LP3907 additionally features programmable sequencing.
