TD351IN datasheet by STMicroelectronics

TD351IN Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in the application note AN4392, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
• How do I calculate the maximum allowed current for the TD351IN?
  The maximum allowed current can be calculated using the formula: I_max = (T_j_max - T_a) / (R_th_j-a * R_th_a), where T_j_max is the maximum junction temperature, T_a is the ambient temperature, R_th_j-a is the junction-to-ambient thermal resistance, and R_th_a is the ambient thermal resistance. Refer to the datasheet for the specific values.
• What is the purpose of the EN (enable) pin, and how do I use it?
  The EN pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to implement power-saving modes or to control the device's operation in specific applications.
• How do I ensure electromagnetic compatibility (EMC) with the TD351IN?
  To ensure EMC, follow the guidelines in the application note AN2679, which provides recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI) and ensure compliance with EMC standards.
• What are the recommended operating conditions for the TD351IN?
  The recommended operating conditions for the TD351IN include an input voltage range of 4.5V to 18V, an output voltage range of 1.2V to 15V, and an operating temperature range of -40°C to 150°C. Refer to the datasheet for specific details.
