Design a Custom BoardAbout This Component
3A synchronous buck converter with 3.8V to 32V input range and integrated 75mΩ high-side and 40mΩ low-side MOSFETs. Features 500kHz switching frequency, 0.8V reference, and enhanced EMI reduction via proprietary gate driver and frequency spread spectrum. Includes UVLO, OVP, and cycle-by-cycle current limiting; AP63301 operates in PWM mode for stable output regulation across all load conditions.
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.
