The input voltage must always be at least 2V higher than the desired output voltage for the module to function correctly. This makes it compatible with a wide variety of DC power sources, from small battery packs to larger industrial supplies.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I select different output voltages on this step-down module?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The module supports four selectable fixed output voltages: 5V, 9V, 12V, and 24V. Output current capacity varies by voltage — 5V\/9V\/12V at up to 2A and 24V at up to 1.7A. Simply configure the output setting before connecting to your circuit.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this DC-DC step down module safe for use in sensitive electronics?\u003c\/h4\u003e\n\u003cp\u003eA: The module features built-in overheat and overload shutdown protection and delivers very low output ripple (under 30mA), making it suitable for many electronics applications. However, it is not designed for use directly with inductive loads like motors or relays without additional components (such as a 100UF\/25V capacitor and TVS diode). Always follow the wiring and usage notes provided.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How compact is this buck converter board?\u003c\/h4\u003e\n\u003cp\u003eA: The board measures just 25.80 × 16.50mm (approximately 1.02 × 0.65 inches), making it one of the most compact step-down converter boards available. Its semi-hole mainboard design makes it easy to solder onto a PCB or mount in tight enclosures.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What input voltage range does this DC-DC buck converter module support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This buck converter module accepts a wide input voltage range of DC 7V to 100V.
