VTX-101-007 - VIGORTRONIX

VTX-101-007 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  The recommended PCB layout involves keeping the input and output tracks separate, using a solid ground plane, and placing the device near a thermal pad or heat sink to dissipate heat. A minimum of 2oz copper thickness is recommended for the PCB.
• How do I ensure the device is properly biased for optimal performance?
  The device requires a stable input voltage and a bias resistor (Rb) to set the output voltage. A recommended bias circuit is provided in the application note, and the resistor value can be calculated using the formula: Rb = (Vin - Vout) / (Iout / 0.9).
• What is the maximum allowable ripple voltage on the input?
  The maximum allowable ripple voltage on the input is 10% of the nominal input voltage. Exceeding this limit may affect the device's performance and stability.
• Can I use the VTX-101-007 in a high-reliability or aerospace application?
  While the VTX-101-007 is a high-quality device, it is not specifically designed for high-reliability or aerospace applications. For such applications, it is recommended to consult with Vigortronix (UK) Ltd or consider using a device with specific certifications (e.g., MIL-STD-883) or compliance with relevant standards (e.g., DO-160).
• What is the typical start-up time for the device?
  The typical start-up time for the VTX-101-007 is around 10-20 ms, depending on the input voltage and output load. This can be affected by the input voltage rise time, output capacitance, and other factors.
