KD1084AD2T18R Frequently Asked Questions (FAQ)

  • STMicroelectronics provides a recommended PCB layout in the application note AN5176, which includes guidelines for thermal pad connection, copper pour, and via placement to ensure optimal thermal performance.

  • 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 ceramic capacitor with an X7R or X5R dielectric.

  • 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 that the voltage on the EN pin does not exceed 6V to prevent damage to the device.

  • The KD1084AD2T18R has a junction temperature (Tj) rating of 150°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to use a heat sink or thermal management system to keep the junction temperature below 125°C for optimal performance and reliability.

  • To ensure stability, follow the recommended PCB layout, use a suitable input capacitor, and ensure that the output capacitor has a low ESR. Additionally, avoid using long traces and minimize the loop area of the feedback network to prevent oscillations.
