AMC7136 - Adjustable Constant Current LED Driver

Description

The AMC7136 is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage.

The current is adjustable from 10mA to 400mA with an external resistor.

Only one external resistor is required to achieve a constant current LED driver.

AMC7136 Adjustable Constant Current LED Driver AMC7136 General Description The AMC7136 is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage. The current is adjustable from 10mA to 400mA with an external resistor. Only one external resistor is required to achieve a constant current LED driver. Soft start, thermal protection and low voltage protection are also provided. A driver pin DR is provided for current and voltage extension. Adding an external NMOS or NPN transistor to this pin can extend current and voltage range. Features y Sink current: 10mA to 400mA adjustable with an external resistor y Current and voltage range extendable by adding an external NMOS or NPN transistor y Power supply voltage: 2.
