OC5224 is a multifunctional average current type LED constant current driver with simple peripheral circuits. It is applicable to the field of high-power dimmable constant current LEDs with step-down BUCK in the voltage range of 5-30V.

The DIM port of the OC5224 supports ultra-small duty cycle PWM dimming, which can respond to pulse widths as small as 60ns. When the DIM port is high, the chip works normally. When the chip is low, the chip output is turned off.

OC5224 adopts average current control algorithm, the output current constant current accuracy is ≤3%, and the output current is less affected by the input and output voltage and system inductance. The chip integrates loop compensation, the peripheral circuit is simple, and the system is more stable and reliable.

The OC5224 is available in a SOT23-6 package.
