Design a Custom BoardAbout This Component
PWM boost converter designed for driving LEDs from single-cell Li-ion or 2-3 AA battery sources. Integrates 1A switch and 1.5MHz oscillator for efficient power management. Typical applications include flashlight drivers, backlight control, and portable LED lighting requiring regulated constant-current output.
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.
