Design a Custom BoardAbout This Component
Synchronous buck converter supporting 4.5V to 36V input with 2A continuous output current in a 6-pin SOT-23 package. Features integrated synchronous rectification, internal compensation, and selectable 500kHz or 1.1MHz switching frequency with PFM/FPWM modes. Includes cycle-by-cycle current limiting, hiccup short-circuit protection, and thermal shutdown for industrial power conditioning applications.
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.
