LF90ABDT-TR Frequently Asked Questions (FAQ)

  • STMicroelectronics provides a recommended PCB layout in the application note AN1071, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).

  • The selection of input and output capacitors depends on the specific application requirements, such as voltage rating, capacitance value, and ESR. STMicroelectronics recommends using X7R or X5R ceramic capacitors with a voltage rating of at least 2x the input voltage and a capacitance value of 10uF to 22uF for the input capacitor, and 10uF to 47uF for the output capacitor.

  • The LF90ABDT-TR is rated for operation up to 125°C ambient temperature, but it's recommended to derate the device for reliable operation above 85°C. Consult the datasheet and application notes for thermal management guidelines.

  • To ensure EMC compliance, follow the guidelines in the application note AN1071, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a metal shield or a shielded inductor to reduce EMI radiation.

  • The recommended input voltage range for the LF90ABDT-TR is 3.5V to 36V, but the device can operate from 2.7V to 40V. However, operating outside the recommended range may affect performance, efficiency, and reliability.
