XCL220B1A3FR-G Frequently Asked Questions (FAQs)

  • Torex recommends a 4-layer PCB with a solid ground plane and a separate power plane for the input and output. The input and output capacitors should be placed as close as possible to the IC, and the feedback resistors should be placed close to the output pin. A detailed layout guide can be found in the Torex application note AN-104.
  • To ensure stability, it's essential to follow the recommended component values and PCB layout. Additionally, the output capacitor should be selected based on the output voltage and current requirements. A minimum output capacitance of 10uF is recommended, and the ESR should be less than 100mΩ. The input capacitor should be at least 1uF with an ESR less than 100mΩ.
  • The maximum ambient temperature for the XCL220B1A3FR-G is 85°C. However, the device can operate up to 105°C with derating. It's essential to follow the thermal design guidelines and ensure proper heat dissipation to prevent overheating.
  • Yes, the XCL220B1A3FR-G is designed to operate in high-vibration environments. However, it's essential to follow the recommended PCB mounting and soldering guidelines to ensure the device is securely attached to the PCB. Additionally, the PCB should be designed to withstand the vibration levels expected in the application.
  • The recommended input voltage range for the XCL220B1A3FR-G is 2.7V to 5.5V. Operating the device outside this range may affect its performance and reliability.
