MEL7136B

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 . 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. Adding an external NMOS or NPN transistor to this pin can extend current and voltage range. Features  MEL7136B is only a controller , and must be connected to an external NMOS.  Sink current:10mA to1A adjustable with an external resistor  Current and voltage range extendable by adding an external NMO...
