The UCC27201ADR can operate up to 1 MHz, but the maximum frequency depends on the specific application and the external component selection.
To minimize EMI, keep the high-frequency components (e.g., the switching node) away from the low-frequency components (e.g., the input and output capacitors). Use a solid ground plane, and keep the traces short and wide. Also, consider using a shielded inductor and a common-mode choke.
The recommended input capacitor value is 10-22 μF, and the type should be a low-ESR ceramic capacitor (e.g., X5R or X7R). The capacitor should be placed close to the VIN pin to minimize noise and ensure stable operation.
The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. For the inductor type, consider using a shielded inductor with a low DC resistance (e.g., a ferrite or iron powder core inductor).
The UCC27201ADR can deliver up to 2 A of output current, but the actual current capability depends on the input voltage, output voltage, and thermal conditions. Be sure to check the thermal derating curves in the datasheet to ensure reliable operation.
