Design a Custom BoardAbout This Component
Synchronous step-down DC/DC converter with 3A output current capability and 2.5V to 5.5V input range. Operates in power save mode at light loads or forced PWM mode with 2.2MHz switching frequency, delivering high efficiency across the load range. Features adjustable output voltage (0.6V to VIN), 1% feedback accuracy, power-good output, and comprehensive protection including overcurrent and thermal shutdown.
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.
