IC LED DRIVER BUCK 40V 1.5A 8MSOP


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardHysteresis-mode DC-DC step-down LED driver supporting 4.5V to 40V input with 1.5A maximum output current in MSOP-8EP package. Integrates 40V power switch and high-side current sensing with external resistor programming. Provides analog/PWM dimming via VSET pin, soft-start control, and comprehensive protection including LED short, open-circuit, and overtemperature detection.
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.
