RT9020-18GB Frequently Asked Questions (FAQs)
-
Richtek provides a recommended PCB layout in their application note AND9231, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
-
To optimize output voltage accuracy and stability, ensure that the input voltage is within the recommended range, use a high-quality output capacitor with low ESR, and minimize the distance between the output capacitor and the RT9020-18GB. Additionally, consider using a voltage reference IC, such as the RT9193, to improve output voltage accuracy.
-
The maximum output current capability of the RT9020-18GB is 18A, but it's recommended to derate the output current based on the ambient temperature and PCB thermal design to ensure reliable operation.
-
The RT9020-18GB has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the overcurrent threshold, and connect the SCP pin to a capacitor that sets the short-circuit detection time. Refer to the datasheet and application notes for detailed implementation guidelines.
-
Richtek recommends using a high-quality, low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The capacitor should be placed close to the VIN pin and have a voltage rating of at least 25V.
