SN57, SN57-On Datasheet - On-Bright Electronics

SN57 High Precision CC/CV Primary-Side PWM Power Switch

SN57 is a high performance offline PSR power switch for low power AC/DC charger and adapter applications. It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as.

SN57 Features

* including Cycle-by-Cycle current limiting, VDD over voltage protection, short circuit protection, built-in leading edge blanking, VDD under voltage lockout (UVLO), OTP etc. SN57 is offered in SOP8 package. FEATURES

* Primary-side sensing and regulation without TL431 and opto-coupler

* High
