Design a Custom BoardSynchronous buck controller IC supporting multiple topologies in 8-pin VSSOP package. Operates from 4.5V to 36V input with integrated high/low side gate drivers. Designed for efficient point-of-load DC-DC conversion with programmable switching frequency and current limiting, commonly used in server, telecom, and industrial power applications.
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
