Design a Custom BoardAbout This Component
Synchronous step-down DC-DC converter delivering up to 3A output current with adjustable output voltage. Integrated high-side and low-side MOSFETs enable efficient power conversion from 4.5V to 18V input. Suitable for battery-powered devices, point-of-load regulation, and embedded systems requiring compact power solutions.
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.
