Design a Custom BoardAbout This Component
Synchronous buck converter with 3V to 17V input range and 4A continuous output capability in a compact 1.6mm × 1.6mm SOT-563 package. Operates in fixed-frequency CCM (FCCM) mode maintaining constant switching frequency and low output ripple across all load conditions. Features integrated MOSFETs, D-CAP3 control, up to 97% duty cycle, and comprehensive protection including OVP, OCP, UVLO, and thermal shutdown for industrial and consumer applications.
Package: SOT-563 · 6 pins
Why does this need a breakout?
The SOT-563's 1.27mm pin pitch and small footprint make hand-soldering difficult and breadboard prototyping impossible. A breakout board brings these pins to standard 0.1" spacing, enabling quick breadboard integration for dual transistors, level shifters, and compact buck converters without requiring SMD soldering skills or microscopy.
