Dc Dc Boost Converter Step Up Constant Current Mobile Power Supply 250W 10A LED Drive

Dc Dc Boost Converter Step Up Constant Current Mobile Power Supply 250W 10A LED Drive

This high-power boost module features adjustable output voltage (DC 10V–50V) and current (up to 6A continuous, 10A max), making it ideal for LED drivers, battery charging, and other power applications. Built on an aluminum substrate that doubles as a heat sink, it is designed for reliable, high-power operation.

With a dedicated benchmark IC and high-precision current sensing resistor, the module offers highly stable current control with minimal temperature drift. The built-in 3296 multiturn potentiometers allow precise voltage and current adjustment.

Package Includes:

  • 1 × 250W High Power Constant Voltage/Current Adjustable LED Driver Module

Specifications and Features:

  • Module Type: Non-isolated Boost (Step-Up) Converter
  • Input Voltage: DC 10V–40V
  • Output Voltage: DC 10V–50V (adjustable, default: 19V)
  • Output Current: 6A continuous, 10A max (heat dissipation required above 4A)
  • Constant Current Range: 0.2A–6A
  • Output Power: Up to 250W (Input Voltage × Output Current)
  • Efficiency: 92%–96%
  • Switching Frequency: 1.2MHz
  • Reverse Input Protection: Yes (below 5A)
  • Mounting: 4 × 3mm screw holes
  • Connection: Screw terminals (VIN+, VIN−, OUT+, OUT−)

Output Voltage / Current Adjustment:

  1. Use RV1 to adjust output voltage to your desired value (e.g., 37V for 10 series LEDs).
  2. Turn RV2 clockwise ~30 turns to minimize current. Connect your load (LED or battery), then increase RV2 to your desired current.
  3. Note: For batteries, discharge them fully before adjustment to ensure accurate current setting.

Warning: Do NOT use a short-circuit method for current adjustment. This module is not designed for that.

Usage Instructions:

  • VIN+ / VIN−: Input voltage terminals
  • OUT+ / OUT−: Output voltage terminals
  • Adjustable Voltage: DC 10V–50V
  • Adjustable Current: 0.2A–6A
  • Min Input Voltage: 10V
  • Max Input Voltage: 40V
  • Ensure input voltage is at least 2V lower than output
  • Before connecting a load: Set voltage and current while no-load
  • Use adequate heat sinking when current exceeds 2A

Precautions:

  • Do not reverse connect input/output terminals
  • Do not exceed maximum voltage, current, or power ratings
  • Ensure proper heat dissipation for prolonged full-load usage
