Description
MEL7136A/MEL7136B Linear Adjustable Constant Current LED Driver MEL7136A/MEL7136B General .
The MEL7136A is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage.
Features
* MEL7136B is only a controller , and must be connected to an external NMOS.
* The output current of ME7136B is adjustable
* Sink current:10mA to1A adjustable with an external
resistor
* Current and voltage range extendable by adding an
external NMOS or NPN transistor
* Power sup
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
