LP3907SQ-TJXIP/NOPB Description
LP3907SQ-TJXIP/NOPB is a multi-function, programmable power management unit (PMU) optimized for low-power FPGAs， microprocessors, and DSPs. This LP3907SQ-TJXIP/NOPB integrates two highly efficient 1-A/600-mA step-down DC-DC converters with dynamic voltage management(DVM), two 300-mA linear regulators, and a 400-kHz I2C interface to allow a host controller access to the internal control registers of the device. The LP3907SQ-TJXIP/NOPB additionally features programmable power-on sequencing.
