A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
Ensure that the input and output capacitors are properly selected and placed close to the device. Also, make sure the PCB layout is well-designed to minimize parasitic inductance and capacitance.
The RT8480GS can handle up to 28V input voltage, but it's recommended to operate within the specified input voltage range (7V to 25V) for optimal performance and reliability.
The output voltage can be adjusted by changing the resistor divider network (R1 and R2) connected to the FB pin. Use the formula provided in the datasheet to calculate the required resistor values.
The EN (Enable) pin is used to turn the device on or off. Connect the EN pin to a logic high (VIN or a voltage above 2.5V) to enable the device, and connect it to a logic low (GND or a voltage below 0.8V) to disable the device.
