The OC5338 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 OC5338 has a built-in 100V /3A power MOS with a fixed turn-off time, which can be adjusted by an external capacitor, so the operating frequency can be set according to user requirements.
The OC5338 sets the output current of the LED through an external resistor.
The OC5338 also integrates a VDD regulator and an over-temperature protection circuit. Reduces external components and improves system reliability.
The OC5338 is available in an ESOP8 package. The heatsink has a built-in SW pin.
