Design a Custom BoardAbout This Component
Synchronous step-down DC-DC converter delivering 4A output from 4.5V to 18V input. Integrates low RDS(ON) MOSFETs, 0.6V reference, and bootstrap diode for compact designs. Features ACOT control architecture for ultrafast transient response, 500kHz switching, cycle-by-cycle current limiting, UVP, UVLO, and OTP protection with 1.5ms soft-start.
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.
