XC9128B45CAR-G Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the IC to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are suggested. Refer to the Torex application note for detailed guidelines.
  • Implement a capacitor filter at the input (e.g., 10uF ceramic capacitor) and ensure the input voltage is within the recommended range (2.5V to 5.5V). Additionally, use a low-ESR output capacitor (e.g., 10uF ceramic capacitor) to minimize output voltage ripple.
  • The maximum allowable ripple voltage on the input is 100mVp-p. Exceeding this may affect the regulator's performance and stability.
  • The XC9128B45CAR-G is rated for operation up to 125°C. However, derating is required for temperatures above 85°C. Consult the datasheet for thermal derating curves and ensure proper heat sinking and thermal management.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the regulator from voltage surges or spikes. Ensure the TVS diode is rated for the maximum expected voltage surge.
