The Buck Converter Stability Demoboard is a compact, easy-to-use platform designed to demonstrate and analyze the stability of a dual-buck converter. It generates 1.8 V and 3.3 V from a 3.5–5.5 V input, making it ideal for labs, training environments, and anyone who wants to visualize real converter behavior.

Instant setup: Power via USB-C and star measuring-status LEDs confirm proper regulation.

Fully configurable: Switchable input damping, compensation networks, output filters, and load settings.

Perfect for education: Compare “good” vs. “bad” stability configurations and instantly see the impact on gain, phase or transient response.

Deep insight: Comprehensive test points give you access to every critical node for loop gain, impedance, PSRR, and step-load analysis.

Built for Bode 100/500: Optimized for use with OMICRON Lab's frequency response analyzers.
