Design a Custom BoardAbout This Component
Hysteresis-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.
Package: TSSOP-8 (3×3mm) · 8 pins
Why does this need a breakout?
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.
