Plusroc Waterproof DC-DC Step-Down Converter

Key Specifications & Features

• Input Voltage: Nominal 12V DC (typically operates across an 8V to 24V range).

• Output Voltage: 5V DC (Fixed or Adjustable depending on module variant).

• Output Current: Usually rated from 1A to 5A (depending on heat dissipation and power design).

• Conversion Efficiency: 85% to 96% high efficiency using switching regulator topologies (e.g., LM2596, MP2307, or KIS-3R33S), generating far less heat than linear regulators like the 7805.

• Form Factors & Interfaces:

  • Bare Modules: Pin headers or solder pads for integration into custom PCB circuits.

  • USB Adapter Modules: Integrated female USB Type-A or Type-C ports for mobile device charging.

  • Enclosed/Hardwired: Potted waterproof casings with wire leads for automotive use.

• Protections: Standard over-current protection, thermal shutdown, and short-circuit protection.

Applications

• Automotive Power Systems: Powering dashcams, action cameras, cell phones, or GPS devices directly from a 12V car battery.

• Embedded Electronics: Supplying a steady 5V logic rail to microcontrollers (Arduino, Raspberry Pi, ESP32) from 12V power supplies.

• Battery-Powered & Solar Projects: Step-down regulation in 12V SLA (Sealed Lead Acid) or LiFePO4 battery banks.
