10 Power Supply Recommendations

The recommended input supply voltage (VCCI) for UCC5304 is between 3 V and 5.5 V. The output bias supply voltage (VDD) range from 9.2V to 18V. The lower end of this bias supply range is governed by the internal under voltage lockout (UVLO) protection feature of each device. One mustn’t let VDD or VCCI fall below their respective UVLO thresholds (For more information on UVLO see VDD, VCCI, and Under Voltage Lock Out (UVLO)). The upper end of the VDD range depends on the maximum gate voltage of the power device being driven by UCC5304. The UCC5304 has a recommended maximum VDD of 18 V.

A local bypass capacitor should be placed between the VDD and VSS pins. This capacitor should be positioned as close to the device as possible. A low ESR, ceramic surface mount capacitor is recommended. It is further suggested that one place two such capacitors: one with a value of ≈10-µF for device biasing, and an additional ≤100-nF capacitor in parallel for high frequency filtering..

Similarly, a bypass capacitor should also be placed between the VCCI and GND pins. Given the small amount of current drawn by the logic circuitry within the input side of UCC5304, this bypass capacitor has a minimum recommended value of 100 nF.
