This DC power converter is a stepdown buck module that accepts a 12V or 24V input and provides a 3.7V output. It is available in multiple current ratings (1A, 2A, 3A, 4A, 5A). This listing is for a single piece unit configured for 12V/24V to 3.7V at 2A. Key benefits Enables using 3.7V devices from common 12V or 24V power sources found in automotive or industrial settings. Simple integration with existing 12V or 24V systems to deliver a dedicated 3.7V supply. Compact, boardbased solution suitable for tight installations and module projects. Key attributes Functionality: DC power converter (stepdown buck) to convert 12V/24V input to 3.7V output. Compatibility: Designed for applications that require a 3.7V supply from higher voltage inputs. Size: Compact form factor suitable for PCB mounting and spaceconstrained installations. Material: Boardbased module constructed with standard PCB materials typical for DCDC converters. Performance: Available in current ratings of 1A, 2A, 3A, 4A, and 5A; this listing is the 2A variant (12V/24V to 3.7V at 2A). Use cases Automotive or industrial electronics that need a 3.7V supply derived from a 12V or 24V power source. Powering a 3.7V Liion based device or battery management component in a compact, dedicated supply. Prototyping and hobby projects where 3.7V operation is required from a higher voltage source without introducing additional regulators. How it solves the problem Provides a direct path from commonly available 12V or 24V sources to a 3.7V output, reducing the need for multiple regulators and simplifying power design for 3.7V devices. Note This description reflects the product's stated specifications: input of 12V/24V, output of 3.7V, current ratings from 1A to 5A, and a 1 piece package for the 12V/24V to 3.7V 2A configuration.
