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 I2 C compatible interface to allow a host controller access to the internal control registers of the LP3907. The LP3907 additionally features programmable power-on sequencing and a tiny 4 x 4 x 0.8mm 24-pin LLP pin package.The LP3907 Evaluation Kit is based on a modular system, where the actual evaluation board is connected to the PC via a USB-I2 C interface board. The kit supports complete functional evaluation of the LP3907 circuit.
