DCDC Step Down Converter Adjustable Power Supply Module 5V 12V 3A Efficiency for Electronics Projects

Adjustable 5V / 12V stepdown power module, selectable by a simple jumper connection. Provides stable lowvoltage output from input voltages up to 35V using efficiency switching regulation with synchronous rectification. Key benefits Selectable output for flexibility: set jumper to shorted for 12V output at 2A, or leave jumper open for 5V output at 3A (factory default is open for 5V). Easy selection without extra components. Wide input range and efficient conversion: accepts up to 35V input and uses synchronous rectification to minimize losses and maintain stable output under load. Reliable stepdown performance: designed specifically for applications that require converting a higher DC voltage to a low, stable supply voltage. Compact module form factor for simple integration into projects and systems where space is limited. Important attributes Function: DCDC stepdown converter with selectable 5V or 12V output modes. Output options: 5V at 3A when jumper is open; 12V at 2A when jumper is shorted. Default configuration is 5V open jumper. Input compatibility: accepts input voltages up to 35V for flexible use with common DC power sources. Performance: switching stepdown topology with efficiency synchronous rectification for improved conversion efficiency and thermal performance. Integration: modulestyle power supply intended for direct incorporation into electronic projects and equipment. Typical applications Powering 5V singleboard computers, microcontrollers, and peripherals that require a stable 5V supply. Supplying 12V devices such as cameras, sensors, and automotive accessories when a higher regulated voltage is needed. Converting vehicle, battery, or industrial DC supplies down to stable 5V or 12V rails for embedded systems, LED lighting, and control units. Usage notes Change output by altering the jumper configuration: short the interface for 12V 2A, leave it disconnected for 5V 3A. The module ships with the jumper open for 5V output. Ensure input voltage does not exceed 35V and observe the output current limits for reliable operation. This module is intended for projects and equipment that require a compact, efficient method to step down higher DC voltages to 5V or 12V with a simple selectable configuration.
