Design a Custom BoardAbout This Component
Adjustable boost regulator IC delivering up to 1.8A output current in a compact SOT-23-5 surface-mount package. Features integrated power switch, error amplifier, and current-limit protection for stepping up input voltage to programmable output levels. Suitable for battery-powered applications, LED drivers, and portable device power management.
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.
