VINGVO Boost Buck Converter DC 5V-32V to 1V-30V 10A Automatic Step-Down Voltage Regulator Load Module LTC3780

VINGVO Boost Buck Converter DC 5V-32V to 1V-30V 10A Automatic Step-Down Voltage Regulator Load Module LTC3780 Popis

Product Features: 1. This is a high-efficiency voltage regulator module. The output voltage remains stable whether the input voltage is lower, higher, or equal to the output voltage. 2. This module has excellent protection functions and can be used for solar charging. 3. The printed circuit board uses a 1.6-layer thickened gold plating process. 4. The input terminal uses a replaceable fuse to protect the power supply and equipment. 5. High-frequency, low-resistance electrolytic capacitors are used, reducing ripple to an extremely low level. 6. It has constant voltage, constant current, and undervoltage protection functions. 7. It uses an iron oxide heat sink for heat dissipation, which is superior to aluminum heat sinks. 8. The inductor is made of iron-silicon-aluminum alloy to reduce heat generation. Specifications: Product Type: Automatic Buck Regulator Input Voltage: DC5-32V (Recommended to be higher than 10V) Output Voltage: DC1V-30V continuously adjustable Output Current: 10A (maximum), 7A (long-term) Output Power: 80W (long-term), 130W (peak). For outputs exceeding 80W, please enhance heat dissipation. Output Ripple: 50mV (measured at 12V, 5A) Short Circuit Protection: Yes Input Reverse Polarity Protection: No. If necessary, connect a Schottky diode at the input. Output Leakage Protection: No. For battery charging or inductive charging, connect a Schottky diode at the output.

Dimensions: 77.6x46.5x15 mm / 3.06x1.83x0.59 inches

Adjustment Method:

1. Battery Undervoltage Protection Adjustment Method: (For example, using a 12V lead-acid battery, set the undervoltage protection to 10V and the output cutoff voltage to 10V.) Rotate counterclockwise until the fault indicator light (red light) illuminates; setting complete. At this point, when the battery discharges to 10V, the power supply will automatically cut off to protect the battery from damage.

Note: This setting is not required if the device is not battery powered.

2. Output Voltage Adjustment Method: Connect the input terminal to the power supply (the voltage must be higher than the undervoltage protection value). The red light will turn off, and the blue light will illuminate.

Connect the output terminal to a multimeter and adjust the output voltage potentiometer to the desired output voltage (clockwise rotation increases, counterclockwise rotation decreases).

Note: Under normal circumstances, the red light will turn off, and the blue light will illuminate.

If this occurs, it indicates a device malfunction; please disconnect the device power supply and then reconnect it.

3. Output Current Adjustment Method: (Taking a 12V lead-acid battery with a 12V input and a 5A charging current as an example)

Connect the input terminal to a 12V power supply, and connect the output terminal in parallel to a multimeter. Adjust the constant current potentiometer (clockwise rotation increases, counterclockwise rotation decreases) until the current display shows 5A. Then disconnect the multimeter and connect the battery for normal charging.

Note: For constant voltage devices, only the maximum output current needs to be set.
