Kadimendium ND0412SA DC-DC Step-up Module

1. Úvod

This manual provides detailed instructions for the Kadimendium ND0412SA DC-DC Step-up Module. This module is designed to convert a lower DC input voltage (2.6V-5.5V) into a higher, stable DC output voltage (selectable 5V, 6V, 9V, or 12V). It is suitable for various applications requiring a boosted power supply, such as battery-powered equipment, LED motors, and low-power electronic devices.

2. Bezpečnostní pokyny

• Ensure all power sources are disconnected before making any connections to the module.
• Observe correct polarity for input and output connections (V_i, GND, V_o). Incorrect polarity can damage the module and connected devices.
• Nepřekračujte stanovený maximální vstupní objemtage or output current ratings.
• Avoid short circuits on the input or output terminals. While the module has short-circuit protection, prolonged short circuits can cause damage.
• Operate the module within its specified temperature range (-40°C to +85°C).
• Keep the module away from moisture, dust, and corrosive environments.

3. Konec produktuview

The ND0412SA is a compact and efficient DC-DC boost converter. It features high efficiency (up to 93%) and incorporates multiple protection mechanisms including over current (OCP), over voltage (OVP), short circuit (SCP), and over temperature (OTP) to ensure reliable operation and extend the lifespan of the power supply.

4. Nastavení

Follow these steps to set up your ND0412SA module:

1. Výstupní objemtage Výběr: Before connecting power, select your desired output voltage (5V, 6V, 9V, or 12V) by bridging the corresponding solder pads on the bottom of the module (refer to Figure 3.2). For example, to set the output to 12V, bridge the pad labeled '12V'. If no pads are bridged, the module may default to a specific voltage or operate unpredictably.
2. Vstupní připojení: Connect your DC input power source to the V_i and GND input terminals. Ensure the input voltage is within the 2.6V to 5.5V range.
3. Výstupní připojení: Connect your load to the V_o and GND output terminals.
4. Advanced Output Voltage and Current Limit Adjustment (Optional): For custom output voltages or current limits, the module allows adjustment via external resistors R1 and R3. This requires soldering and precise resistor values. Refer to Figure 4.1 for details.
   • Výstupní objemtage (R1): The R1 resistor sets the output voltage. The formula is R1(KΩ) = 10 * (Vout / 0.6 - 1).
   • Current Limit (R3): The R3 resistor programs the peak switch current. The resistor value should be between 10kΩ and 100kΩ. The current limit will be set from 2.5A to 0.5A. The formula is I_in = 48000 / R3.

5. Návod k obsluze

Jakmile je modul správně zapojený a výstupní hlasitosttage is selected, apply power to the input terminals. The module will automatically boost the input voltage to the selected output voltage. Monitor the output voltage and current to ensure it meets your application's requirements and stays within the module's specifications.

6. Údržba

• Udržujte modul čistý a bez prachu a nečistot.
• Ensure adequate ventilation, especially when operating at higher loads, to prevent overheating.
• Pravidelně kontrolujte spoje, zda nejsou uvolněné nebo korozi.
• Avoid physical shock or excessive vibration to the module.

7. Řešení problémů

• No Output Voltage:
  • Zkontrolujte vstupní objtage, abyste se ujistili, že je v rozsahu 2.6V-5.5V.
  • Verify input and output connections for correct polarity and secure contact.
  • Zajistěte výstupní objtage selection pads are correctly bridged.
  • Check for any short circuits on the output. The module's SCP may have activated.
• Nesprávný výstupní objemtage:
  • Re-verify the output voltage selection pads.
  • If using custom R1 adjustment, double-check resistor value and soldering.
• Přehřátí modulu:
  • Reduce the load connected to the output.
  • Ensure proper ventilation around the module.
  • Zkontrolujte, zda vstupní voltage is too low, causing the module to draw excessive current.
• Přerušovaný provoz:
  • Check for loose connections or poor soldering.
  • Ensure the module is not exposed to excessive electromagnetic interference.
