Design a Custom BoardAbout This Component
Adjustable synchronous buck regulator delivering up to 3A output current in a compact TSOT-23-8 package. Supports input voltages from 4.5V to 18V with programmable output voltage via external resistor divider. Features integrated high-side and low-side MOSFETs for high efficiency step-down conversion, suitable for portable electronics and automotive applications.
Package: TSOT-23-8 · 8 pins
Why does this need a breakout?
The 0.95mm pin pitch and compact footprint make hand-soldering extremely difficult and breadboard incompatible. A breakout board brings all eight pins to standard headers, enabling reliable prototyping of precision analog ICs like DACs, op-amps, and current-sense amplifiers without specialized soldering equipment.
