OC5020B is a high-efficiency, high-precision switching step-down high-power LED constant current driver IC with built-in 100V power MOS.
OC5020B Peak current control with fixed turn-off time, the turn-off time can be adjusted by an external capacitor, and the operating frequency can be changed according to user requirements.
OC5020B By adjusting the external current sensing resistor, the driving current of the high-brightness LED lamp can be controlled to achieve the expected constant brightness.
Add a PWM signal on the DIM side to dim the LED light. The DIM side also supports linear dimming OC5020B The VDD regulator and over-temperature protection circuit are also integrated to reduce external components and improve system reliability.
OC5020B is available in an ESOP8 package. The heatsink has a built-in SW pin.
