The 12V to 4.2V DCDC Buck Converter provides a fixed 4.2V output from a wide input range of 8 to 36V, delivering up to 1A. This buck regulator is designed for reliable, stepdown conversion in applications where a stable 4.2V rail is required from higher voltage sources. Key benefits Flexible input range: accepts 8–36V DC, enabling use with automotive, industrial, and batterypowered systems. Stable 4.2V output: suitable for Liion cell related circuits and other devices that require a 4.2V supply. Up to 1A continuous current: supports midpower loads. Simple integration: dropin component for projects that need a fixed 4.2V supply. Efficient power conversion: reduces heat compared with linear regulation by stepping down voltage. Key specifications Model: 12V to 4.2V DCDC Buck Converter (8V36V Input, 1A Output) Type: Buck DCDC converter Input voltage range: 8–36V DC Output voltage: 4.2V DC Maximum output current: 1A Use cases Powering Liion battery charging circuits: provide a stable 4.2V reference from a higher voltage source such as a vehicle 12V system or a lab supply. Supplying 4.2V loads in automotive or industrial equipment: sensors, microcontrollers, or small modules that require a precise 4.2V rail. Laboratory or prototyping: create a compact 4.2V supply from 12V or higher to test Liion cells and related electronics. Notes Ensure input remains within 8–36V and output current does not exceed 1A. This device provides a fixed 4.2V output. It is a regulator, not a standalone charger circuit.
