UCC2800DG4 Frequently Asked Questions (FAQ)
-
A good PCB layout for the UCC2800DG4 involves keeping the high-frequency components (such as the transformer and the power MOSFETs) close together, using a solid ground plane, and keeping the signal traces short and direct. Additionally, it's recommended to use a shielded transformer and to place the UCC2800DG4 close to the transformer to minimize radiated emissions.
-
When choosing a transformer for the UCC2800DG4, consider the output power, output voltage, and input voltage requirements. The transformer's turns ratio, inductance, and core material should be selected based on the specific application. A good starting point is to use a transformer with a turns ratio of 1:1.2 to 1:1.5, and an inductance of 10-20 μH. The core material should be a ferrite or iron powder core with a high saturation flux density.
-
The UCC2800DG4 can handle output powers up to 150 W, depending on the input voltage, output voltage, and transformer design. However, the maximum output power is limited by the thermal performance of the device, and the recommended maximum output power is around 100 W to ensure reliable operation.
-
The UCC2800DG4 has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the ISENSE pin and ground. The value of the resistor determines the overcurrent threshold. A good starting point is to use a 1 kΩ resistor, which sets the overcurrent threshold to around 1 A. The UCC2800DG4 will shut down if the current exceeds this threshold.
-
The VCC pin on the UCC2800DG4 is the power supply pin for the internal control circuitry. It should be connected to a stable 5-15 V power supply, and a decoupling capacitor (typically 1-10 μF) should be connected between VCC and ground to filter out noise and ensure stable operation.
