DC-DC Converter Circuit Diagram Examples
Designing a DC‑DC converter requires a clear circuit diagram to ensure proper component selection, layout, and functionality. This gallery features ready‑to‑use circuit schematics for the most common DC‑DC converter topologies—buck, boost, SEPIC, and isolated flyback—each tested with real component values and configurations.
Describe it in plain English — the AI drafts it, you edit. No template wrangling.
About these examples.
Whether you're prototyping a battery charger, building a power supply, or integrating regulation into an IoT device, these examples give you a head start. You can copy any diagram directly into our online circuit diagram maker to adapt voltages, swap components, or add your own notes—no software installation required.
Make one yourself.
Choose a topology
Decide whether you need step‑down (buck), step‑up (boost), buck‑boost (SEPIC), or isolated conversion (flyback) for your power supply requirements.
Select the core IC and passive components
Browse our library of common converter ICs (like LM2596, LT1370) and drag in inductors, capacitors, diodes, and resistors.
Connect nodes and verify the circuit
Use the smart‑wiring tool to link components; the editor highlights missing connections to avoid floating nodes.
Customize labels and values
Annotate pin functions, add voltage/current notes, and adjust component values to match your specific design.
