Description

This AC-DC reference design is a flyback converter with secondary-side regulated (SSR) and constant current (CC) output. The input voltage range can be set to low-line by a jumper wire.The output load ranges from 11 V to 21 V and it is intended to be used for 9 V to 18 V battery charging.

Features

SSR with adjustable CC output up to 4 AOutout load range from 11 V to 21 V21 V eff. 92% @ 230 VAC, 90% @ 110 VACStandby power < 250 mW @ 230 VAC

Typical applications

Battery charger
cordless power tools
Battery Chargers, Cordless power tools
Battery Chargers, Cordless power tools
