Kadimendium ND0412SA DC-DC Step-up Module

1. Pengenalan

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. Arahan Keselamatan

• 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.
• Jangan melebihi vol input maksimum yang ditentukantage 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. Produk Lebihview

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. Persediaan

Follow these steps to set up your ND0412SA module:

1. Keluaran Voltage Pemilihan: 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. Sambungan Input: 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. Sambungan Output: 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.
   • Keluaran Voltage (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. Arahan Operasi

Once the module is correctly wired and the output voltage is selected, apply power to the input terminals. The module will automatically boost the input voltage to the selected output voltage. Pantau keluaran voltage and current to ensure it meets your application's requirements and stays within the module's specifications.

6. Penyelenggaraan

• Pastikan modul bersih dan bebas daripada habuk dan serpihan.
• Ensure adequate ventilation, especially when operating at higher loads, to prevent overheating.
• Regularly inspect connections for looseness or corrosion.
• Avoid physical shock or excessive vibration to the module.

7. Penyelesaian masalah

• Tiada Keluaran Voltage:
  • Semak input voltage to ensure it is within the 2.6V-5.5V range.
  • Verify input and output connections for correct polarity and secure contact.
  • Pastikan keluaran voltage selection pads are correctly bridged.
  • Check for any short circuits on the output. The module's SCP may have activated.
• Voltan Output Salahtage:
  • Re-verify the output voltage selection pads.
  • If using custom R1 adjustment, double-check resistor value and soldering.
• Modul Terlalu Panas:
  • Reduce the load connected to the output.
  • Ensure proper ventilation around the module.
  • Periksa sama ada input voltage is too low, causing the module to draw excessive current.
• Operasi sekejap:
  • Check for loose connections or poor soldering.
  • Ensure the module is not exposed to excessive electromagnetic interference.
