DC-DC Step-Down Converter 600W 25A — Adjustable 12–75V → 2.5–60V (CC/CV)
Overview
The DC-DC Step-Down 600W 25A converter reduces voltage from 12–75V to 2.5–60V and allows adjustment of both voltage (CV) and current (CC). It offers high efficiency, current-limit protection, and is ideal for controlled power supply, battery charging (with flyback diode), testing, and DIY projects.
Advantages
- Precise voltage and current adjustment.
- Compatible with input sources up to 75V.
- High efficiency up to 95%.
- Quick control via VIADJ and IADJ potentiometers.
Technical Specifications and Key Features
Parameter
Value
Maximum Power
600W (500W recommended continuous)
Output Current
1–25A
Input Voltage
12–75V
Output Voltage
2.5–60V (step-down only)
Modes
CV (constant voltage) / CC (constant current)
Efficiency
Up to 95%
Operating Frequency
80 kHz
Indicator
Blue LED (output voltage)
Short-Circuit Protection
Current limiting (CC)
Load Compatibility
Batteries, small motors, electronic modules
Warnings
No reverse polarity protection; flyback diode required for inductive loads
Adjustment Instructions
- Use a multimeter for calibration.
- VIADJ: clockwise = higher voltage; counterclockwise = lower voltage.
- IADJ: start at minimum (10 turns counterclockwise), then increase to desired current.
- Do not directly connect input ground to output ground.
- The module operates strictly as step-down.
Best Practices
- Check polarity before connecting.
- Use a flyback diode with motors.
- Provide cooling for high loads.
Applications
- Battery charging (with flyback diode)
- Powering modules, small motors, converters
- Laboratory and testing
- DIY projects and automation
Package Contents
- 1 × 600W 25A Step-Down Module
Can I increase the voltage?
No. The module operates only as step-down; VOUT must be lower than VIN.
What happens if I reverse polarity?
There is no protection. Disconnect immediately and reconnect correctly.
Is a diode required for motors?
Yes. Inductive loads require a flyback diode to protect the module.
