This 12V to 3.3V DCDC Buck Converter is a compact power module designed to reliably convert a higher DC voltage to a stable 3.3V output. With an input range of 8V to 36V and an output capability of up to 3A, it provides a versatile solution for powering 3.3V logic and devices from a variety of power sources. Key benefits Converts 836V input to 3.3V output up to 3A, enabling use from 12V, 24V, and other supply rails. Delivers up to 3A continuous current to medium load applications. Simple integration in compact enclosures thanks to its straightforward buck conversion design. Provides a dedicated 3.3V supply for microcontrollers and sensors, reducing the need for multiple voltage rails. Key attributes Functionality: DCDC buck converter that steps down voltage to 3.3V. Compatibility: Accepts input in the 8V–36V range and outputs 3.3V for compatible loads. Size and build: compact design suitable for spaceconstrained installations; PCBbased power module. Performance: 3A maximum output current; designed to deliver a stable 3.3V rail from higher voltage sources. Use cases Automotive or industrial electronics: power a 3.3V microcontroller or sensor suite from a 12V or 24V power source within the 836V input range. Embedded systems prototyping: feed a 3.3V rail for development boards, microcontrollers, and peripherals from a bench supply or vehicle power line. Remote monitoring: supply 3.3V regulators for edge devices in remote or harsh environments where higher voltage rails are available. Notes Designed to convert from 836V to 3.3V at up to 3A; ensure the 3.3V load does not exceed 3A at your operating conditions. Use appropriate wiring and distribution to maintain voltage integrity.
