OB2211, OB2211-On Primary-Side Regulation PWM Power Switch

OB2211 Description

OB2211/OB2212 Primary-Side Regulation PWM Power Switch GENERAL .
OB2211/OB2212 is an offline PWM Power switch for low power AC/DC charger and adaptor applications.

OB2211 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

OB2211 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 integrated as shown in the figure below. In CC control, the current and output power setting can be adjust
