Design a Custom BoardAbout This Component
Adjustable buck converter regulator IC in 10-pin HVSSOP package rated for 500mA output current. Features integrated high-side and low-side power switches with typical switching frequency of 1.5MHz, enabling compact external component designs. Suitable for isolated and non-isolated DC-DC conversion applications in battery-powered and industrial systems.
Package: MSOP-10 (P0.5mm) · 10 pins
Why does this need a breakout?
The 0.5mm pin pitch makes hand soldering impractical without specialized equipment, and the tiny 3x3mm footprint cannot connect directly to breadboards. A breakout board brings these pins to standard 0.1-inch spacing, enabling rapid prototyping of analog-to-digital converters, boost controllers, and audio switches without reflow soldering or custom PCBs.
