MEL7136A/MEL7136B Linear Adjustable Constant Current LED Driver MEL7136A/MEL7136B General Description The MEL7136A is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage. The current is adjustable from 10mA to1A with an external resistor. The MEL7136B is only a controller , and must be connected to an external NMOS. MEL7136B is an external transistor, is suitable for applications requiring a high output current . The output current of ME7136B can be adjusted by external DC control voltage or PWM control. Only one external resistor is required to achieve a constant current LED driver. Soft start , thermal protection and low voltage protection are also provided. The driver pin EXT is provided for current and voltage extension.
