The OC5330 is a three-function switched, step-down LED constant current driver. Switching between functions can be switched on and off by turning the power supply on and off: full light (100%) – dark (25%) – flash.
The OC5330 has a built-in 100V/100m2 power MOS and a fixed turn-off time control that can be adjusted by an external capacitor, so the operating frequency can be set according to the user’s requirements.
The OC5330 sets the output current of the LED through an external resistor.
The OC5330 also integrates a VDD regulator tube, an over-temperature protection circuit, and more. Reduces external components and improves system reliability.
The OC5330 is available in an ESOP8 package. The heatsink has a built-in SW pin.
