MPM4730 Overview
The MPM4730 is a synchronous, four-switch integrated buck-boost module with a 2.8V to 22V input voltage (VIN) range. The device regulates the output voltage (VOUT) with high efficiency, and provides integrated VOUT scaling and output current (IOUT) limit functions. The MPM4730 uses constant-on-time (COT) control in buck mode and constant-off-time control in boost mode, providing a fast load transient response and...
