MMP20100 is a power management integrated circuit (IC) manufactured by STMicroelectronics. The circuit is used for providing regulated and switched power for a range of applications. It integrates a high-efficiency step-down converter, a linear regulator, and four power MOSFET drivers in a single package. The step-down converter operates over an input voltage range of 4.5V to 60V and has an adjustable output voltage range of 0.8V to 5V. It also includes an enable input, a power good output and an enable lock-out function. Additionally, the device has an adjustable switching frequency from 200kHz to 2.2MHz and programmable soft start, slope compensation and over-current protection features. This integrated circuit is ideal for powering microcontrollers, FPGAs, memory, and other digital logic circuits.
