| Description:
The LP3906 is a multi-function, programmable Power Management Unit, optimized for low power FPGAs, Microprocessors, and DSPs. This device integrates two highly efficient 1.5A Step-Down Dc/Dc converters with dynamic voltage management (DVM), two 300mA Linear Regulators and a 400kHz 12C compatible interface to allow a host controller access to the internal control registers of the LP3906. The LP3906 additionally features programmable power-on sequencing and is offered in a tiny 5 x 4 x 0.8mm LLP-24 pin package.
The LP3906 Evaluation kit is based on a modular system, where the actual evaluation board is connected to the PC via a USB-I2 C interface board. The kit supports complete functional evaluation of the LP3906 circuit.

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.
