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.
