Product details

Description

Pin Name Type Description 1 FB INPUT Feedback: Reference voltage is 200 mV.The cathode of the LED and a resistor to ground to set the LED current should be connected at this point.A "5% metal film resistor, or better, is recommended for best output accuracy.An analog signal can be applied to this input to dim the LED.2 COMP INPUT Loop Compensation: A frequency compensation network must be connected between this pin to the ground to ensure the stability of the closed loop.See “
