T1035H-6I datasheet by STMicroelectronics

T1035H-6I Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in their application note AN5046, which includes guidelines for thermal pad connection, copper pour, and via placement to ensure optimal thermal performance.
• How do I select the correct input capacitor for this device?
  The input capacitor selection depends on the input voltage, ripple current, and ESR requirements. STMicroelectronics recommends using a low-ESR ceramic capacitor with a value between 1uF to 10uF, and a voltage rating of at least 1.5 times the input voltage.
• What is the maximum allowed voltage on the enable pin?
  The enable pin (EN) can withstand a maximum voltage of 6V, which is the same as the maximum input voltage of the device. Applying a voltage higher than 6V can damage the internal circuitry.
• Can I use this device in a high-temperature environment?
  The T1035H-6I 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 performance and lifespan.
• How do I ensure the device is properly powered up and down?
  To ensure proper power-up and power-down, STMicroelectronics recommends using a soft-start circuit to limit the inrush current and prevent voltage overshoots. Additionally, the enable pin should be driven with a low-impedance source to ensure a clean and fast transition.
