Design a Custom BoardAbout This Component
Synchronous buck converter with 3V to 17V input range and adjustable 0.6V to 10V output. Delivers up to 3A continuous current with integrated 55mΩ/24.3mΩ MOSFETs and D-CAP3 control mode for fast transient response. The TPS563257 variant operates in FCCM mode for constant frequency and lower ripple across all load conditions. Includes thermal protection, cycle-by-cycle current limiting, and integrated bootstrap capacitor for compact single-layer PCB designs.
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.
