Primary Side Regulation PWM Power Switch

OB221X series are offline PWM power switch ICs. They are designed for primary side regulation with minimum overall system cost by removing X/Y caps, Photo-coupler and TL431. They include an internal error amplifier to delivery high performance CC/CV control. OB2211/OB2212 is highly recommended for ·Primary side sensing and regulation eliminates TL431 and photo-coupler\n·External adjustable gate drive capability\n·Enable no-X and no-Y system design\n·Low system cost\n·Built-in error amplifier for CV/CC operation \n·External adjustable CC operation\n·Low standby power\n·Frequency shuffling redu;
