OB5682TASP Description
OB5682x is a primary side regulation off-line LED lighting power switch which can achieve accurate LED current. It significantly simplifies LED lighting system design by eliminating the secondary side feedback circuitry, HV startup resistor and power supply capacitor. LED current (CC control) can be adjusted by the external sense resistor connected between CS pin and ground.
