IC BUCK CONVERTER 3A 18V TSOT-23-6


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardSynchronous step-down DC-DC converter supporting 4.5V to 18V input with 3A output capability and integrated MOSFETs. Features Advanced Constant On-Time control for fast transient response, 500kHz switching frequency, and comprehensive protection including cycle-by-cycle current limiting, thermal shutdown, and UVLO. Ideal for automotive, industrial, and portable applications requiring compact, efficient power conversion.
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.
