LDK320ADU30R Frequently Asked Questions (FAQ)

  • STMicroelectronics provides a recommended PCB layout in the application note AN4979, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.

  • The input capacitor selection depends on the input voltage, ripple current, and ESR requirements. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and an ESR of less than 1 ohm. STMicroelectronics recommends using a capacitor with a capacitance value between 10uF to 22uF.

  • The maximum allowed voltage drop across the internal resistance (Rds(on)) of the LDK320ADU30R is typically around 1.5V to 2V. Exceeding this voltage drop may lead to overheating and reduced reliability.

  • The LDK320ADU30R is rated for operation up to 150°C, but it's essential to ensure proper thermal management and derating to prevent overheating. Consult the datasheet and application notes for guidance on thermal derating and design considerations for high-temperature applications.

  • To ensure EMC, follow proper PCB design practices, such as using a solid ground plane, minimizing loop areas, and using shielding or filtering components as needed. Additionally, consider using a common-mode choke or EMI filter at the input stage to reduce electromagnetic interference.
