Design a Custom BoardAbout This Component
Synchronous step-down converter with 4.5V to 28V input range and 3A continuous output current. Integrates dual MOSFETs (85mΩ high-side, 40mΩ low-side), internal compensation, and soft-start in compact SOT-23 package. Features 400kHz fixed switching frequency with spread spectrum for EMI reduction, Eco-mode pulse-skip for light-load efficiency, and comprehensive protection including cycle-by-cycle current limiting and hiccup-mode overcurrent detection.
Package: TSOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
