OB2538, OB2538-On Datasheet (On-Bright Electronics) - High Precision CC/CV Primary-Side PWM Controller

OB2538 - High Precision CC/CV Primary-Side PWM Controller

OB2538 is a high performance offline PWM Power switch for low power AC/DC charger and adaptor 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

OB2538 Features

* including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique. High precision constant voltage (CV) and constant current (CC) can be achieved by OB2538. . FEATURES

* 5% Constant Voltage
