1 / 38 page LP3906 Dual High-Current Step-Down DC/DC and Dual Linear Regulator with I2C Compatible Interface General Description The LP3906 is a multi-function, programmable Power Man- agement Unit, optimized for low power FPGAs, Microproces- sors 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 se- quencing and is offered in a tiny5x4x 0.8mm LLP-24 pin package.
