Instructions for UCC3804DTR

1. Supply Voltage (Vcc):

   • Connect the supply voltage to pin 7 (Vcc). The recommended operating range is 12V to 30V.
   • Ensure that the input voltage does not exceed the maximum rating to avoid damage to the device.

2. Under-Voltage Lockout (UVLO):

   • The UVLO feature prevents the device from operating if the supply voltage drops below 10V (typical).
   • This helps protect the circuit from malfunctioning during low-voltage conditions.

3. Over-Voltage Protection (OVP):

   • The OVP feature shuts down the device if the supply voltage exceeds 36V (typical).
   • This protects the device and the connected circuit from overvoltage conditions.

4. Oscillator Configuration:

   • Set the oscillator frequency by connecting a resistor (Rosc) between pin 5 (RT/CT) and ground.
   • Use the formula ( f_ = frac{1}{1.1 times R_ times C_} ) to determine the frequency, where ( R_ ) is in ohms and ( C_ ) is in farads.

5. Current Limit:

   • The current limit is set by the voltage on the CS pin (pin 3).
   • The typical current limit is 1A when Vcs = 1V. Adjust the current sense resistor accordingly.

6. Error Amplifier:

   • The error amplifier compares the feedback voltage with a reference voltage.
   • Connect the feedback voltage to pin 1 (FB) and the reference voltage to pin 2 (REF).

7. Soft-Start:

   • Implement soft-start by connecting a capacitor (Css) between pin 4 (SS) and ground.
   • The typical soft-start time is 2ms for a 1μF capacitor.

8. Dead Time:

   • The dead time is the time during which both high-side and low-side switches are off to prevent shoot-through.
   • The typical dead time is 0.5μs.

9. Thermal Shutdown:

   • The device will automatically shut down if the junction temperature exceeds 150°C (typical).
   • Ensure proper heat dissipation to avoid thermal shutdown.

10. Operating Temperature:

    • The device can operate in temperatures ranging from -40°C to 125°C.
    • Ensure that the ambient temperature is within this range to maintain reliable operation.

11. Layout Considerations:

    • Keep the layout compact to minimize parasitic inductance and capacitance.
    • Use wide traces for power connections to reduce resistance and improve heat dissipation.

By following these instructions and parameters, you can ensure that the UCC3804DTR operates efficiently and reliably in your application.
