Design a Custom BoardAbout This Component
Adjustable boost regulator IC with 3A switch current, integrated 80mΩ power switch, and 8-WSON package. Supports input voltage 2.5V-6V with adjustable output up to 28V via external resistor divider. Commonly used in battery-powered applications, LED backlighting, and portable consumer electronics requiring step-up voltage conversion.
Package: DFN-8 (2×2mm) · 8 pins
Why does this need a breakout?
Hand-soldering 0.5mm pitch pads is extremely difficult without specialized equipment, and the exposed leads cannot access a breadboard. A breakout board with standard 0.1" headers lets you prototype high-voltage DC-DC converters like the MAX15062 without requiring reflow soldering or custom PCBs, making rapid iteration practical for industrial and sensor applications.
