OB2212

Primary-Side Regulation PWM Power Switch

OB2212 Features

* including Cycle-by-Cycle current limiting, VDD over-voltage clamp and UVLO, fail-safe protection for open loop fault condition. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output with

OB2212 General Description

OB2211/OB2212 is an 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 from design. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrat.
