TSH350ILT datasheet by STMicroelectronics

TSH350ILT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in the application note AN5093, which includes guidelines for thermal pad connection, thermal vias, and copper pouring to ensure optimal thermal performance.
• How do I select the correct input capacitor for the TSH350ILT?
  The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a capacitance value between 1uF to 10uF, and a voltage rating at least 1.5 times the input voltage. Additionally, the capacitor's ESR (Equivalent Series Resistance) should be low enough to minimize voltage ripple.
• What is the maximum allowed voltage on the enable pin (EN)?
  The maximum allowed voltage on the enable pin (EN) is 6V, as specified in the datasheet. Exceeding this voltage may damage the device.
• Can I use the TSH350ILT in a high-temperature environment?
  The TSH350ILT is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and ensure proper heat dissipation to maintain the device's junction temperature within the recommended range.
• How do I troubleshoot the TSH350ILT if it's not functioning as expected?
  Start by verifying the input voltage, output voltage, and enable pin (EN) voltage. Check for proper PCB layout, thermal design, and component selection. Use an oscilloscope to monitor the output voltage and input voltage ripple. Consult the datasheet and application notes for troubleshooting guidelines and FAQs.
