illustrate

The LP3907 is a multifunctional, programmable power management unit with low-power FPGAs, microprocessors, and DSP optimizations. The device integrates dynamic voltage management (DVM) for two high-efficiency 1A/600mA 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 LP3907 of the internal control registers. In addition, the LP3907 features programmable on-power sequencing. Package options include a tiny 4× 4 ×0.8 mm LLC 24-pin package and a smaller 2.5 × 2.5 mm micro SMD 25 bump package.
