A702 is an adjustable constant current driver for LED applications. Six regulated current ports are designed to provide uniform and pure DC constant current sinks for driving LEDs within a large range V F variations. Users may adjust the output current from 5mA to 40mA through an external resistor that gives user flexibility in controlling the light intensity of LEDs. The wide supply voltage range of 6V~50V is suitable for various applications and the output sustaining voltage of 75V makes it capable of driving up to 35pcs of LED in series. The very thin package of QFN -3 ¡Ñ 3 is especially suitable in LED backlight applications.

The AMC7140 is a high voltage, adjustable low dropout current regulator for high power LEDs. Users may adjust the output current from 100mA and up to 700mA through an external resistor that gives user flexibility in controlling the light intensity of LEDs. The wide supply voltage range of 5V~50V is suitable for various applications. The output sustaining voltage of 75V is highest in the market that makes it capable of driving up to 35pcs of LED in series. The very high voltage rating is especially suitable in lighting and LED backlight applications for LCD TV.
