Design a Custom BoardAbout This Component
Synchronous buck converter with 4.5V to 36V input range and 3A continuous output current in a compact SOT-23 package. Features adjustable output voltage, 500kHz/1.1MHz switching frequency options, internal compensation, and integrated protection including cycle-by-cycle current limiting and hiccup-mode short circuit protection. Suitable for industrial applications including appliances, building automation, motor drives, and general-purpose power supplies.
Package: SOT-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.
