Design a Custom BoardAbout This Component
High-efficiency synchronous buck converter with 3.8V to 28V input range and adjustable 0.8V to 22V output up to 3A. Features 500kHz fixed-frequency peak current control, integrated MOSFETs, 20µA quiescent current, and comprehensive protection (OCP, OVP, UVP, OTP). Ideal for distributed power systems in industrial, consumer, and portable applications.
Package: SOT-583-8 · 8 pins
Why does this need a breakout?
SOT-583-8 packages are extremely difficult to hand-solder due to their 0.5mm pin pitch and small form factor. A breakout board brings these 8 pins to standard 0.1" spacing, making prototyping with power management ICs like synchronous buck converters and power multiplexers feasible without specialized equipment.
