Design a Custom BoardAbout This Component
Adjustable buck-boost switching regulator IC in 8-SOIC package capable of 750mA output current. Accepts 2.5V to 40V input and regulates to adjustable output voltage via external resistor divider. Integrated PWM controller with current limiting and thermal shutdown for step-up or step-down DC-DC conversion applications.
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.
