Automatic Boost Buck Power Module High Power Adjustable DC Voltage Regulator Board

Core Competitive Advantages vs Ordinary XL6009/LM2577 Modules

1. Higher Voltage Safety Margin
   Traditional modules only use single 40V SS34 diode, which cannot meet the buck-boost circuit voltage requirement (device withstand voltage ≥ input+output max voltage). This board uses dual parallel 60V SS56 Schottky diodes + 60V high-current MOSFET, safe for 30V full-range input & output without breakdown risk.
2. Stronger Continuous Load Capacity
   Ordinary SS34 diode only supports actual continuous current below 3A with severe heating; dual SS56 parallel design achieves stable 3A natural cooling output, up to 4A high current with auxiliary heat dissipation.
3. Higher Conversion Efficiency & Less Heat
   High-performance iron-silicon aluminum magnetic ring inductor greatly reduces inductance loss, the whole board runs cooler under full load, efficiency up to 88%, much better than hot ordinary winding inductors.
4. Complete Built-in Protection Circuits
   Integrated short-circuit protection and undervoltage lockout protection, automatically cut off output under fault conditions to protect the module and rear-end electrical equipment.

Wiring & Operation Guide

1. Power Input: Connect DC 5.5~30V power supply to IN+ / IN- terminals, strictly distinguish positive and negative poles (no reverse connection protection onboard).
2. Voltage Adjustment: Rotate the blue trim potentiometer clockwise to raise output voltage, counterclockwise to lower it, output range 0.5~30V.
3. Load Connection: Connect your electrical load to OUT+ / OUT- terminals; this module is constant voltage type, not recommended for battery charging or constant current LED driving.
4. Full Load Reminder: To reach full 30W output power, input voltage needs to be ≥7V; output power is limited to ~15W when input is 5.5V.

Built-in Protection Mechanism Explanation

1. Short-circuit Protection: Automatically shut down output when short circuit occurs; restore normal work after re-powering the module. It is recommended to add a fuse at the input if your power supply lacks current limiting function.
2. Undervoltage Protection: Cut off output automatically when input voltage drops below 5V, avoid abnormal low-voltage operation; re-power to recover after input voltage returns to normal range.

Application Scenarios

• Electronic DIY & Laboratory Adjustable Power Supply
• Industrial Equipment Wide Voltage Conversion (unstable input voltage 5.5~30V, fixed voltage output)
• Camera, Motor, Single-chip Microcontroller Power Conversion
• Vehicle Electrical Equipment Voltage Stabilization
• Robot, Monitoring Equipment Power Regulator Module

Important Usage Notes

1. This is a constant voltage module, not suitable for constant current scenarios such as lithium battery charging and high-power LED driving.
2. The rated power of the input power supply must be higher than the required output power of the load.
3. No reverse polarity protection at the input end, strictly confirm positive and negative wiring to avoid burning the module.
4. Long-term full-load operation requires additional heat sink to avoid overheating damage.
5. Product appearance and parameters may be updated without prior notice, subject to the physical product.
