The LP3906 is a multi-function, programmable Power Management Unit, optimized for low power FPGAs, Microprocessors and DSPs.
This device integrates two highly efficient 1.5A 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 LP3906. The LP3906 additionally features programmable power-on sequencing and is offered in a tiny 5 x 4 x 0.8mm WQFN-24 pin package.
