MPQ4430 Datasheet (MPS) - Step-Down Converter

MPQ4430, Step-Down Converter

The MPQ4430 is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated internal highside and low-side power MOSFETs.

It provides up to 3.5A of highly efficient output current with current mode control for fast loop response.

MPQ4430 Features

* include soft start (SS), external clock synchronization, enable (EN) control, and a power good (PG) indicator. Highduty cycle and low dropout mode are provided for automotive cold-crank condition. Over-current protection (OCP) with valleycurrent detection is employed to prevent the inductor current
