illustrate

The LP3906 is a multi-functional, programmable power management unit with a low-power FPGA, microprocessor, and DSP optimization. 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 master controller to access the LP3906 of the internal control registers. In addition, the LP3906 features programmable electrical sequencing in a tiny 5 x 4 x 0.8 mm LLP-24-pin package.
