JW®1121A is a current mode monolithic buck LED driver. Operating
with an input range of 4.2V-20V, JW1121A delivers 1.5A of continuous output
current with two integrated N-Channel MOSFETs. The internal synchronous power
switches provide high efficiency without the use of an external Schottky diode.
It incorporates analog dimming mode and PWM signal to analogy dimming mode onto
a single control pin.
JW1121A guarantees robustness with LED short protection, thermal protection, start-up
current run-away protection, input under voltage lockout.
JW1121A is available in 6-pin SOT23 packages, which provide a compact solution
with minimal external components.
