UCC2802QDRQ1 Frequently Asked Questions (FAQ)

  • A good PCB layout for the UCC2802QDRQ1 involves keeping the input and output stages separate, using a star-ground configuration, and placing the input and output capacitors close to the IC. Additionally, using a ground plane and minimizing trace lengths can help reduce EMI.

  • The choice of input and output capacitors for the UCC2802QDRQ1 depends on the specific application requirements. In general, low-ESR capacitors with a high ripple current rating are recommended. A minimum capacitance of 10uF is recommended for the input capacitor, and 22uF for the output capacitor.

  • The UCC2802QDRQ1 has an operating ambient temperature range of -40°C to 125°C. However, the maximum junction temperature is 150°C, and the device should be derated above 85°C to ensure reliable operation.

  • The UCC2802QDRQ1 has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OC pin and the input voltage. The value of the resistor determines the overcurrent threshold. Additionally, an external current sense resistor can be used to monitor the output current and implement overcurrent protection.

  • The recommended input voltage range for the UCC2802QDRQ1 is 8V to 18V. However, the device can operate with input voltages as low as 6V, but with reduced performance and efficiency.
