The 48V to 19V DCDC Stepdown Converter is a constant voltage power converter that accepts 30V to 60V DC input and provides a stable 19V output at up to 6A. It is a buck (stepdown) converter designed to transform higher voltage sources into a reliable 19V supply for devices that require a fixed voltage. Key benefits Delivers a stable 19V output from a 30V–60V DC source, helping protect connected equipment from voltage fluctuations. current capability up to 6A, allowing operation of laptops or other devices that require 19V and up to 114W total power. Simple integration for systems that use higher voltage DC rails, including automotive, industrial, and solar configurations. Helps unify power sources: convert diverse 30V–60V supplies to a common 19V level for compatible equipment. Key attributes Functionality: DCDC buck converter with constant voltage output Input range: 30V to 60V DC Output voltage: 19V DC Maximum output current: 6A Output power (maximum): 114W Design type: Stepdown (buck) converter Application focus: Providing a fixed 19V supply from higher voltage DC sources What to know for compatibility and use Suitable for devices that require a stable 19V supply capable of drawing up to 6A. Works with DC sources in the 30V–60V range, such as highervoltage battery configurations, DC power rails, or solar / industrial DC supplies. Ensure proper wiring and polarity for reliable operation and verify that the connected load does not exceed the 19V/6A rating. For results, maintain input within the specified range and provide adequate heat dissipation as needed by your installation. Use cases Case 1: Powering a 19V laptop or 19V portable monitor from a 48V vehicle battery, solar power system, or other 30–60V DC source. Case 2: Supplying 19V control electronics or embedded development boards in an industrial or lab setting from a higher voltage DC distribution bus. Case 3: Providing a fixed 19V supply for telecom or automation equipment that requires a stable 19V input when the available source is within the 30–60V range. Notes The converter is designed to deliver a steady 19V output at up to 6A from any compatible 30V–60V input source. Check that the input source can consistently supply the required current for your load. No additional features such as adjustable output voltage or listed protections are specified; follow standard safe installation practices for DCDC converters.
