A 4-layer PCB with a solid ground plane and thermal vias is recommended. The RT8077GQW's thermal pad should be connected to the ground plane using multiple thermal vias.
Ensure that the input voltage is within the recommended range, and the output capacitor is of sufficient value and type (e.g., X5R or X7R ceramic). Also, ensure that the feedback network is properly designed and connected.
The maximum allowable input voltage ripple is 10% of the input voltage. Exceeding this may affect the regulator's stability and output voltage regulation.
Yes, but ensure that the junction temperature (TJ) does not exceed 125°C. The device's power dissipation should be derated according to the ambient temperature to prevent overheating.
Use a TVS (transient voltage suppressor) diode or a voltage clamp circuit at the input to protect the regulator from voltage surges and spikes.
