Description for the LP3907

The LP3907 device isa multi-function, programmable power management unit (PMU) optimized for low-power FPGAs,microprocessors, and DSPs. This device integrates two highly efficient 1-A, 600-mA step-down DC-DCconverters with dynamic voltage scaling (DVS), two 300-mA linear regulators, and a 400-kHzI2C interface to allow a host controller access to the internal controlregisters of the device. The LP3907 additionally features programmable power-on sequencing.

Features include programmable power-on sequencing, communication control (I2C), dynamicvoltage scaling, overcurrent protection, Power Good, synchronous rectification, thermal shutdown,and undervoltage lockout. For applications requiring light loads, the high-efficiency synchronousswitching buck regulators enter PFM mode and operate with reduced switching frequency and supplycurrent to maintain high efficiency at very light loads.
