Design files

Overview

PMP4370 converts 12Vdc voltage to non-isolate negative 5V5A. Full feature synchronous PWM buck controller TPS40170 and CSD87350 are combined together to achieve the inverting buck-boost topology. The efficiency is >92% @ full load. PMP4370 has extra low output ripple and noise(<20mV) that it can be used in noise sensitive application, like medical application.
