OC5232B 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 5-60V.

The DIM port of OC5232B supports PWM dimming with an ultra-small duty cycle and can respond to a minimum pulse width of 60ns. When the DIM port is at a high level, the chip works normally. When it is at a low level, the chip output is turned off.

OC5232B adopts average current control algorithm. The constant current accuracy of output current is ≤±5%, and the output current is less affected by input and output voltages and system inductance. The chip integrates loop compensation internally. The peripheral circuit is simple and the system is more stable and reliable.

OC5232B is packaged in SOT89-5.
