Design a Custom BoardAbout This Component
High-efficiency step-down DC-DC converter with adjustable output voltage (0.8V to 5.5V) and integrated 1.5A switch. Operates from 4.5V to 17V input with integrated soft-start and overcurrent protection. Ideal for portable electronics, industrial equipment, and low-power supply applications requiring compact form factor.
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.
