OC5028B is a high-power LED constant current driver IC with built-in 100V power MOS, high efficiency and high precision.
OC5028B 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.
OC5028B 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 of the LED lamp.
Add a PWM signal on the DIM side to dim the LED light. The DIM side also supports linear dimming OC5028B The VDD regulator and over-temperature protection circuit are also integrated to reduce external components and improve system reliability.
OC5028B is available in an ESOP8 package. The heatsink has a built-in SW pin.
