Description: OB2216 Primary-Side Regulation PWM Power Switch GENERAL DESCRIPTION OB2216 is a n offline PWM Power switch for low powe r AC/DC charger and adaptor application s. It operates in primary-side sensing and regulation. Consequently, opto-coup ler and TL431 could be eliminated. Prop rietary Constant Voltage (CV) and Const ant Current (CC) control is integrated as shown in the figure below. In CC con trol, the current and output power sett ing can be adjusted externally by the s ense resistor Rs at CS pin. In CV contr ol, multi-mode operations are utilized to achieve high performance and high ef ficiency. Device operates in fixed freq uency mode at large load conditions, fr equency reduction mode at light/medi
