MEL7136
Adjustable Constant Current LED Driver MEL7136
General Description
The MEL7136 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.
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.
