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.
Features
Sink current:10mA to1A adjustable with an external
resistor
Current and voltage range extendable by adding an
external NMOS or NPN transistor
Power supply voltage: 2.7-18V
Low drop out voltage: 50mV@1A
Low quiescent current: 80uA
Thermal Shutdown protection165
Soft start
Low voltage protection: 2.5V
