8.4 Power Supply Recommendations

The recommended input supply voltage (VVIN) for UCC14341-Q1 is between 13.5V and 16.5V. To help ensure reliable operation, adequate decoupling capacitors must be located as close to supply pins as possible. Local bypass capacitors must be placed between the VIN and GNDP pins at the input; between VDD and VEE at the isolated output supply; and COM and VEE at the lower voltage output supply. TI recommends low ESR, ceramic surface mount capacitors. Table 8-2 provides the recommended capacitance for high frequency decoupling. The input supply must have an appropriate current rating to support output load required by the end application.
