The QX7136 is a constant current regulator for
driving LEDs with low quiescent current and low
dropout voltage. The current is adjustable from
10mA to 400mA 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.
A driver pin DR is provided for current and
voltage extension. Adding an external NMOS or
NPN transistor to this pin can extend current and
voltage range.
