LP3907SQX-JXQX/NOPB Description

The LP3907SQX-JXQX/NOPB is a multi-function, programmable power management unit (PMU) optimized for low-power FPGAs， microprocessors， and DSPs. This LP3907SQX-JXQX/NOPB integrates two highly efficient 1-A， 600-mA step-down DC-DC converters with dynamic voltage scaling (DVS), 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 LP3907SQX-JXQX/NOPB additionally features programmable power-on sequencing.
