Design a Custom BoardAbout This Component
The AP3211 is a 1.4MHz fixed-frequency buck converter delivering up to 1.5A with adjustable output from 0.81V to 15V and input range of 4.5V to 18V. It integrates a low-RDS(on) N-channel MOSFET, current-mode PWM control, and built-in protections including over-current, over-voltage, thermal shutdown, and soft-start. Ideal for portable electronics and LCD applications requiring efficient step-down power conversion.
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.
