LED DRIVER BUCK 40V 1.5A 8MSOP-EP


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardAutomotive-grade hysteresis mode buck LED driver supporting 4.5V to 40V input and up to 1.5A output current for driving single or multiple series LEDs. Integrates 40V NDMOS switch with high-side current sensing, offers >95% efficiency, PWM/DC dimming control via VSET pin, and comprehensive protection including short-circuit and thermal shutdown. AEC-Q100 Grade 1 qualified.
The 0.65 mm pin pitch makes hand soldering tedious and error-prone; a breakout board lets you solder standard headers instead, enabling quick prototyping on breadboards. Ideal for I2C GPIO expanders, level translators, and audio amplifiers where you need reliable connections without rework risk.
