Design a Custom BoardAbout This Component
High-efficiency PWM step-down DC/DC converter delivering 1A output current from 2.8V to 5.5V input range with adjustable output (0.6V to VIN). Features integrated synchronous rectifier eliminating need for external Schottky diode, 1.5MHz fixed switching frequency, and 95% efficiency. Ideal for portable battery-powered applications including cellular phones, PDAs, and portable instruments.
Package: TSOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
