11V to 18V IN, 0.4A OUT Non-Synchronous Buck Converter

Overview

TopologyBuck Converter
Input voltage11-18 V
Output 18.4 V / 0.4 A
IC revision1.0

Description

The EV9472-J-00A is the evaluation board ofMPS’MP9472 non-synchronous buck converter.The board has a continuous output current upto 0.4A. The output voltage is preset to 8.4V,but can be easily adjusted to other levels from0.923V. Current mode control provides fasttransient response and cycle-by-cycle currentlimit. Fault condition protections includecycle-by-cycle current limiting, thermalshutdown and under-voltage lockout.Programmable soft-start reduces turn-on stress.Small TSOT23-8 package minimizes boardarea.
