Design a Custom BoardAbout This Component
Automotive-compliant synchronous buck converter with 3.8V to 32V input range and fixed 3.3V output at 2A continuous current. Integrates high-side (125mΩ) and low-side (68mΩ) power MOSFETs for efficient DC-DC conversion with 1100kHz switching frequency. Features EMI reduction via proprietary gate driver and frequency spread spectrum, plus cycle-by-cycle current limiting and thermal shutdown protection.
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.
