Hot-selling and scarce LP3907QSQ-JXIP Dual High-Current Step-Down DC-DCAnd Dual Linear Regulator MSOP8 spot stock

Product Descriptions

The LP3907-Q1 is a multi-function,  programmable Power Management  Unit,  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 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 LP3907 -Q1 additionally features programmable power-on sequencing.  This device is an Automotive-Grade Product that is AECQ-100 Grade 1 Qualified.
