ZHCSK90D september 2019 – january 2021 UCC12050
PRODUCTION DATA
The recommended input supply voltage (VINP) for the UCC12050 is between 4.5 V and 5.5 V. To help ensure reliable operation, adequate decoupling capacitors must be located as close to supply pins as possible. Place local bypass capacitors between the VINP and GNDP pins at the input, and between VISO and GNDS at the isolated output supply. Low ESR, ceramic surface mount capacitors are recommended. It is further suggested that one place two such capacitors: one with a value of 10 μF for supply bypassing, and an additional 100-nF capacitor in parallel for high frequency filtering. The input supply must have an appropriate current rating to support output load required by the end application.
