TC1264-1.8VDBTR Frequently Asked Questions (FAQs)

  • Microchip recommends following a star-grounding layout, keeping the device away from high-current carrying traces, and using a solid ground plane to minimize noise. Additionally, place decoupling capacitors close to the device and use a low-ESR capacitor for the output capacitor.
  • To ensure stability, ensure the output capacitor is within the recommended range (10uF to 22uF), the input capacitor is at least 1uF, and the device is operated within the recommended input voltage range. Also, avoid using a capacitor with high ESR and ensure the PCB layout is well-designed to minimize parasitic inductance.
  • The TC1264-1.8VDBTR is designed to operate up to 6V input voltage. Exceeding this voltage may cause damage to the device. It's recommended to add input voltage protection, such as a voltage regulator or a transient voltage suppressor, to prevent overvoltage conditions.
  • The TC1264-1.8VDBTR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the device's output current and voltage according to the temperature derating curve provided in the datasheet.
  • To troubleshoot issues, first verify the input voltage and current, and ensure the device is operated within the recommended specifications. Check the PCB layout for any noise or parasitic inductance issues. Use an oscilloscope to measure the output voltage and current, and verify the output capacitor is within the recommended range. If issues persist, consult the datasheet and application notes or contact Microchip's technical support.
