Design a Custom BoardAbout This Component
Adjustable step-down (buck) switching regulator with 500mA output current capability in a 10-pin HVSSOP surface-mount package. Designed for efficient DC-DC conversion from input voltages up to 18V with programmable output voltage via external resistor network. Commonly used in portable electronics, battery-powered systems, and low-power applications requiring compact form factors.
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.
