A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The input and output capacitors should be placed close to the IC, and the feedback resistors should be placed close to the output pin.
To ensure stability, the output capacitor should be a low-ESR type, and the feedback resistors should be chosen to ensure a stable gain margin. Additionally, the input and output capacitors should be decoupled from the power plane to prevent noise coupling.
The maximum input voltage that the RT8068AZQW can handle is 28V, but it's recommended to keep the input voltage below 24V to ensure reliable operation.
The RT8068AZQW is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's recommended to use a heat sink or thermal pad to ensure reliable operation in high-temperature environments.
The output voltage of the RT8068AZQW can be calculated using the formula: Vout = (1 + R2/R1) * Vref, where R1 and R2 are the feedback resistors, and Vref is the internal reference voltage (1.25V).
