DER-580 - 118 W High Line Input Non-PFC CV/CC Flyback Charger Power Supply

DER-580 - 118 W High Line Input Non-PFC CV/CC Flyback Charger Supply

Overview

This engineering report describes a 59 V (nominal), 118 W flyback reference design for operation from 180 VAC to 264 VAC supplies. The power output is designed with constant voltage/constant current characteristics for battery charger applications. The charging circuit is optimized for lead-acid batteries. When the current drops below ~0.5 A during charging, the output voltage switches the 59 V charge voltage to the 56 V float voltage to keep the battery charged without overcharging. This is a standard feature of lead acid battery chargers. The design is based on the TOP267EG without PFC input stage. It is designed to operate without a fan and features a thermal switch that reduces the current limit at high temperatures (thermal foldback), allowing continuous charging at reduced output current without the need for thermal shutdown.
