The LP3907 is a multi-function, programmable Power Management Unit, optimized for low power FPGAs, microprocessors and DSPs. This device integrates two highly efficient 1A/ 600mA step-down DC/DC converters with dynamic voltage management (DVM), two 300mA linear regulators and a 400kHz I2C compatible interface to allow a host controller access to the internal control registers of the LP3907. The LP3907 additionally features programmable power-on sequencing. Package options include a tiny 4 x 4 x 0.8mm LLP 24pin package and an even smaller 2.5 x 2.5mm micro SMD 25-bump package.
