OB2500N, OB2500N-On Datasheet (On-Bright Electronics) - High Precision CC/CV Primary-Side Power Switch

OB2500N, OB2500N-On, High Precision CC/CV Primary-Side Power Switch

OB2500N 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
