Design a Custom BoardAbout This Component
High-efficiency buck converter IC designed for driving LEDs from 4.5V to 40V input supplies. Integrates a 40V power switch with 1A output capability and high-side current sensing for TSOT-25 package. Supports DC voltage or PWM dimming control via the CTRL pin, with soft-start and protection features including LED short/open-circuit detection and thermal shutdown.
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.
