Design a Custom BoardAbout This Component
PWM boost converter IC designed to drive LEDs from a lower input voltage. Delivers up to 1A output current with programmable regulation, supporting input voltages from 0.5V to 5.5V. Operates at 1.2MHz switching frequency with integrated power switches, suitable for flashlight, camera flash, and general LED lighting applications.
Package: SOT-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.
