illustrate

The LP3906 is a multifunctional, programmable power management unit with a low-power FPGA, microprocessor, and DSP optimization. The device integrates dynamic voltage management (DVM), two 300mA linear regulators, and two high-efficiency 1.5A BUCK DC/DC converters at 400kHz, i 2 The C-compatible interface allows the main controller to access the LP3906 of the internal control registers. The LP3906 is also featured in a power-up sequence programmable in a miniature 5× 4 × 0.8 mm LLP - 24-pin package.
