9.3 Power Supply Recommendations

The device is designed to operate from an input voltage supply range between 2.7V and 5.5V. To help facilitate reliable operation at data rates and supply voltages, a 0.1μF bypass capacitor is recommended on the VCC power supply pin. Place the capacitor within 2mm of the VCC pin and as close to the VCC pin as possible.

If only a single primary-side power supply is available in an application, isolated power can be generated for the secondary-side with the help of an isolation transformer driver, such as Texas Instruments' SN6501, SN6505A/B, or SN6507. For such applications, detailed power supply design and transformer selection recommendations are available in the data sheets for each of these products and the respective product webpages on TI.com.
