T1035-6G-TR - STMicroelectronics

T1035-6G-TR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in their application note AN4923, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
• How do I select the correct input capacitor for the T1035-6G-TR?
  The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the input voltage, and a capacitance value between 1uF to 10uF. Refer to the application note AN4923 for more detailed guidance.
• What is the maximum allowed voltage on the enable pin (EN)?
  The enable pin (EN) has a maximum allowed voltage of 6V, which is higher than the recommended operating voltage of 5V. However, it's essential to ensure the EN pin voltage does not exceed 6V to prevent damage to the device.
• Can I use the T1035-6G-TR in a high-temperature environment?
  The T1035-6G-TR has a junction temperature (Tj) rating of 150°C, but the device can operate up to 125°C ambient temperature with proper heat sinking and thermal management. It's essential to ensure the device does not exceed the maximum junction temperature to prevent thermal shutdown or damage.
• How do I calculate the output voltage ripple of the T1035-6G-TR?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. Refer to the application note AN4923 for more detailed information.
