Download the OB2211H datasheet PDF.
This datasheet also covers the OB2211H-On variant, as both devices belong to the same primary-side pwm power switch family and are provided as variant models within a single manufacturer datasheet.
General Description
OB2211H 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.
Key Features
including Cycle-by-Cycle current limiting, VDD clamp and UVLO. Excellent EMI performance is achieved wi.
Note: The manufacturer provides a single datasheet file (OB2211H-On-BrightElectronics.pdf) that lists specifications for multiple related part numbers.

OB2211H 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. 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 adjusted externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency. Device operates in fixed frequency mode at large load conditions, frequency reduction mode at light/m
