The OC5331 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 OC5331 is controlled with a fixed turn-off time, which can be adjusted by an external capacitor, so the operating frequency can be set according to the user’s requirements.
The OC5331 uses an external resistor to set the output current of the LED.
The OC5331 also integrates a VDD regulator tube, an over-temperature protection circuit, and more. Reduces external components and improves system reliability.
The OC5331 is available in a SOT23-6 package.
