Design a Custom BoardAbout This Component
Continuous-mode buck converter IC designed for efficiently driving single or multiple series-connected LEDs from 6V to 60V input supplies. Delivers up to 550mA adjustable output current with typical 0.8% accuracy and achieves up to 97% efficiency, supporting up to 30W output power. Features PWM dimming capability on the ADJ pin and inherent LED open-circuit protection, qualified to automotive AEC-Q100 Grade 1.
Package: TSOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
