RS2111/RS2112
Primary-Side Regulation PWM Power Switch
Description
RS2111/RS2112 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 integrated as shown in the figure below.

Typical CC/CV Curve 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 ach...
