OC7201 is a single-line step-down LED constant current driver, only an external resistor can form a complete LED constant current drive circuit, adjusting the external resistor can adjust the output current, the output current range is 10mA~2400mA. The OC7201 has built-in over-temperature protection to protect the chip from damage caused by overheating.
The OC7201 has a very low quiescent current of 60uA typical.
OC7201 supports DIM analog dimming function, by inputting an analog voltage of 0~1.1V on the DIM pin, adjust the LED current, when the VDIM voltage is greater than 1.1V, the output current will keep the maximum current working.
The OC7201 has built-in input overvoltage protection.

Applications
Linear IED illumination drive
LED Flashlight, LED Desk Lamp, LED Miner’s Light, LED Indicator, etc
Car headlights
