illustrate

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