    • Description

    The LP3907 is a multi-function, programmable Power Management Unit, optimized for low power FPGAs, microprocessors and DSPs. This device integrates two highly efficient 1A/600mA step-down DC/DC converters with dynamic voltage management (DVM), two 300mA linear regulators and a 400kHz I 2C compatible interface to allow a host controller access to the internal control registers of the LP3907. The LP3907 additionally features programmable power-on sequencing. Package options include a tiny 4 x 4 x 0.8mm LLP 24-pin package and an even smaller 2.5 x 2.5mm micro SMD 25-bump package.

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
