Design a Custom BoardSynchronous buck regulator with adjustable output voltage from 0.8V to 5.5V, delivering up to 2A continuous current. Integrated high-side and low-side MOSFETs enable efficient DC-DC conversion with minimal external components. Ideal for powering microcontrollers, sensors, and battery-powered systems.
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.
