The LP3907-Q1 device is a 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-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 LP3907-Q1 additionally features programmable power-on sequencing. This device is an Automotive-Grade Product that is AECQ-100 Grade 1 Qualified.
Features include programmable power-on sequencing, communication control (I2C), dynamic voltage scaling, overcurrent protection, Power Good, synchronous rectification, thermal shutdown, and undervoltage lockout. For applications requiring light loads, the high-efficiency synchronous switching buck regulators enter PFM mode and operate with reduced switching frequency and supply current to maintain high efficiency at very light loads.
