12V to 19V 1A Y1 Voltage Regulator Boost Power Converter (NonIsolated) Key benefits Converts a 12V DC source into a regulated 19V DC output, providing a straightforward solution when only a 12V supply (battery or vehicle) is available but 19V is required. Delivers up to 1A output current, allowing reliable power for small devices that need 19V without changing the primary power source. Nonisolated design keeps input and output grounds common, simplifying wiring and integration in systems where common ground is acceptable. What this unit does and why you need it Functionality: DCDC boost (stepup) regulator that raises 12V to a stable 19V output. Problem solved: avoids the need for separate 19V power supplies or batteries by converting an existing 12V source to 19V quickly and efficiently at low to moderate current levels. Unique point: model Y1 explicitly targeted for compact boost conversion from 12V to 19V with a 1A capability and a nonisolated topology for simple system integration. Key attributes Model: Y1 Type: Voltage regulator boost power converter (DCDC stepup) Input/Output: designed to use a 12V DC input and provide a regulated 19V DC output Output current: up to 1A Isolation: nonisolated (input and output share common ground) Use environment: suitable where a common ground is acceptable and where the 1A current limit meets device requirements Practical considerations and installation notes Observe correct input polarity. Reversing polarity may damage the converter. Because the module is nonisolated, ensure the common ground is compatible with your system before connecting. Do not exceed the rated output current (1A). Overcurrent can overheat the unit or trigger protection (if present). Provide adequate ventilation or mounting to avoid heat buildup during sustained operation. Verify device power requirements (voltage and current) before use to ensure compatibility. Typical applications (use cases) Powering a 19V device from a 12V car or marine battery: use the Y1 module to run small 19V equipment from an automotive 12V source without changing the vehicle wiring or adding a separate 19V adapter. Running 19V peripherals from a 12V DC supply in field equipment or portable setups: ideal for small monitors, routers, or other electronics that require 19V at currents up to 1A. Converting 12V backup/LED power systems to supply 19V control electronics: useful in projects where a single 12V battery must serve devices with different voltage needs and common grounding is acceptable. What to check before buying Confirm your device requires 19V and draws 1A or less. Confirm that a nonisolated converter (common ground) is acceptable for your application. Check physical mounting and connector needs in your system (wiring, polarity, and ventilation). This Y1 12Vto19V 1A boost regulator offers a simple, focused solution for stepping up 12V DC to a regulated 19V DC output when a commonground, compact converter is required.
