Key Differentiators
- Enhanced start-up and transient response (vs UCC28019D)
- Low start-up current (<200 Β΅A) (vs UCC28019D)
- Fixed 65-kHz frequency (vs UCC28060DR)
Design Notes
For optimal performance, place the UCC28019ADR close to the power stage. Keep the gate drive trace short and wide to minimize inductance and ringing. Use a Kelvin connection for the current sense resistor to avoid noise pickup. Ensure a solid ground plane under the IC to reduce EMI.
The VCC pin should be bypassed with a 0.1 Β΅F ceramic capacitor placed as close as possible to the pin. Additionally, a 10 Β΅F electrolytic capacitor may be needed to supply the gate drive current. The VIN pin should be connected to the rectified AC line through a resistor divider to sense input voltage for feed-forward.
The UCC28019ADR is a controller and dissipates minimal power, but ensure adequate copper area around the IC for heat dissipation. The SOIC-8 package has a thermal resistance of approximately 150Β°C/W. In high-temperature environments, consider derating the operating temperature and providing airflow.
