A 4-layer PCB with a solid ground plane and thermal vias is recommended. The RT8058GQW's thermal pad should be connected to a large copper area on the PCB to dissipate heat efficiently.
To ensure stable output voltage regulation, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to place the output capacitor close to the RT8058GQW.
The maximum input voltage that can be applied to the RT8058GQW is 18V, but it is recommended to operate within the specified input voltage range of 7V to 15V for optimal performance and reliability.
The RT8058GQW has built-in overcurrent protection (OCP) and thermal shutdown (TSD) features. However, it is still recommended to add external overcurrent protection and thermal monitoring to ensure the device operates within safe limits.
A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor, placed close to the RT8058GQW's input pins.
