IC REG BUCK ADJ 4A SOT23-6


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardStep-down DC-DC converter with adjustable output voltage from 0.8V to 5.5V at up to 4A continuous current. Integrated synchronous rectification and integrated MOSFETs enable high efficiency conversion in a compact footprint. Suitable for portable power supplies, industrial equipment, and embedded system rail generation with input range up to 17V.
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.
