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.
