OC522C is amulti-function average-current LED constant current driver with simple peripheral circuits, suitable for step-down buck high-power dimming constant current LED applications in the voltage range of  5-100V.
The PWM port of the OC522C supports ultra-small duty cycle PWM dimming and responds to pulse widths as small as 60ns. When the PWM port is high, the chip works normally. When the chip is low, the chip output is turned off.
OC522C 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 OC522C is available in a SOP8 package.
