illustrate

The LP3906 is a versatile, programmable power management unit, low-power FPGA, microprocessor, and DSP optimized. The device integrates dynamic voltage management (DVM) for two high-efficiency 1.5A step-down DC/DC converters, two 300mA linear regulators, and a 400kHz I 2 The C-compatible interface allows a host controller to access the LP3906 of the internal control registers. The LP3906 also features programmable power-on sequencing and is a tiny 5 x 4 x 0.8 mm LLP - 24-pin package.
