The FNYUVNFAF 48V to 19V DCDC Stepdown Module Converter is a buck converter that turns a 3060V DC input into a stable 19V output at up to 5A. It provides constant voltage to drive 19V devices from higher voltage sources, helping to simplify power design in a variety of applications. Key benefits Delivers a steady 19V output from a wide input range (3060V), enabling flexible sourcing from different DC buses or batteries. Supplies up to 5A, making it suitable for mid range 19V loads while maintaining a constant voltage. Keeps output voltage stable, protecting sensitive electronics from input fluctuations and transients. Module form factor enables straightforward integration into power supplies, control panels, or other equipment without the need for a dedicated linear regulator. Supports applications that require a reliable 19V supply derived from higher voltage sources, reducing the need for multiple power stages. Key attributes Model: FNYUVNFAF Type: DCDC stepdown (buck) module with constant voltage output Input voltage range: 30V to 60V DC Output voltage and current: 19V DC, up to 5A (maximum power approximately 95W) Functionality: Constant voltage power conversion from higher voltage input to a fixed 19V output Form factor: Module designed for integration into electronic equipment and assemblies Material and exact dimensions: Not specified in the listing; designed for compact module integration Compatibility and integration Suitable for systems and devices that require a stable 19V supply from a higher voltage DC source. Compatible with applications where a single, reliable 19V rail is needed from a 3060V input so additional regulation stages are minimized. Use cases Use case 1: Power a 19V laptop, display, or other 19V device from a 48V DC battery or power bus in a portable or field setup. Use case 2: Provide a stable 19V supply for an embedded computer or controller in an industrial equipment enclosure powered by a 60V DC bus. Use case 3: Supply 19V to telecom, digital signage, or similar equipment from a higher voltage DC distribution system, reducing the need for multiple regulators. Notes Input must remain within 3060V DC, and the load should not exceed 5A to maintain the specified 19V output. The exact size, housing material, and connector details are not provided in the available specification; the unit is described as a compact module designed for integration into electronic assemblies. Ensure proper thermal management and electrical safety practices when integrating the module into equipment.
