IC REG BUCK ADJ 2A 8-SOIC


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardSynchronous buck converter IC with adjustable output voltage supporting up to 2A load current. Operates from 4.5V to 28V input with integrated high and low-side MOSFETs, delivering efficient DC-DC conversion. Suitable for battery charging, industrial power supplies, and automotive applications requiring compact regulation.
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.
