84 W AC-DC reference design for battery chargers with 110 VAC / 230 VAC rated input and CC output up to 4 A
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.
Summary of Features
SSR with adjustable CC output up to 4 A
Outout load range from 11 V to 21 V
21 V eff. 92% @ 230 VAC, 90% @ 110 VAC
Standby power < 250 mW @ 230 VAC
Benefits
High eff. & low EMI with QR operation
Configurable brown-in and -out levels
Adaptive brown-out to protect components
QR operation for high efficiency
Comprehensive set of protections
Potential Applications
Battery chargers
Cordless power tools
