Design a Custom BoardAbout This Component
Adjustable buck-boost switching regulator controller IC in 8-SOIC package capable of delivering 1.5A output current. Supports both step-up and step-down voltage conversion with external transistor and diode. Operates from 3V to 40V input with adjustable output voltage set via resistive divider. Ideal for battery-powered systems requiring flexible voltage regulation.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
