: 1/9 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.
V0 8-Lead Plastic DIP-8 Package Code: P  8-Lead Plastic SOP-8 Package Code: S I0 Fig1.
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...
