Description
MP4433 36V, 3A, Low Quiescent Current, Synchronous, Step-Down Converter .
The MP4433 is a synchronous, step-down, switching regulator with programmable frequency (350kHz to 2.
Features
* include soft start, external clock synchronization, enable control, and power good indication. High-duty cycle and low dropout mode are provided for automotive coldcrank. Over-current protection (OCP) with valleycurrent detection is employed to prevent the inductor current from running away. Hiccup
Applications
* in automotive input environments. The MP4433 is ideal for battery-powered applications due to its extremely low quiescent current. The MP4433 employs advanced asynchronous mode (AAM) to achieve high efficiency in lightload condition by scaling down the switching frequency to reduce switching and gat
