OB5628AJPA

OB5628A Non-isolated Power Switch with HV Startup GENERAL DESCRIPTION FEATURES OB5628A is a high current precision, non-isolated power switch with HV startup for LED lighting application. It works under transition mode.  It simplifies the LED lighting system design by eliminating the auxiliary winding inductance and HV startup resistor. A 500V power switch is integrated in OB5628A. LED current can be adjusted by the external sense resistor connected between CS pin and ground.  OB5628A offers comprehensive protection coverage with auto-recovery features including cycle-by-cycle current limiting, built-in leading edge blanking, over temperature protection (OTP), etc.       HV startup Sense and supply without auxiliary winding inductance Low System Cost and High Efficiency Low operation current Transition mode operation Cycle-by-Cycle Current Limiting Built-in Leading Edge Blanking (LEB) Over temperature protection (OTP) APPLICATIONS  LED lighting OB5628A is offered in SOP7/SOT23-5/SOT33-4 package.
