10 Power Supply Recommendations

To help ensure reliable operation at data rates and supply voltages, TI recommends connecting a 1-µF bypass

capacitor at the input and output supply pins (VCC1 and VCC2). The capacitors should be placed as close to the

supply pins 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 a transformer driver such as TI's SN6501 device. For

such applications, detailed power supply design and transformer selection recommendations are available in

SN6501 Transformer Driver for Isolated Power Supplies. (SLLSEA0).
