The 24V to 4.2V DCDC Buck Converter Module is a compact power module that steps down an input voltage in the 8–36 V range to a fixed 4.2 V output, capable of delivering up to 2 A. It is designed for use in automotive, industrial, and general purpose applications where a stable 4.2 V rail is required from a highervoltage source. Key benefits Reliable fixed 4.2 V output from a wide input range (8–36 V), suitable for Liion battery related circuits and other 4.2 V applications. Up to 2 A continuous current to support moderateload devices and modules. Compact module form factor for easy integration into projects, enclosures, or onto a PCB. Simple way to create a dedicated 4.2 V rail from common power sources such as 12 V or 24 V supplies. Key attributes Functionality: DCDC buck converter module with a fixed 4.2 V output. Input range: 8–36 V DC. Output: 4.2 V DC, up to 2 A. Compatibility: Suitable for automotive, industrial, and general purpose power sourcing where a 4.2 V rail is required.
