UCC28050D Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a compact layout with the UCC28050D placed close to the resonant capacitor and the transformer. The layout should also minimize the loop area of the high-frequency currents to reduce EMI. A good starting point is to follow the layout guidelines provided in the UCC28050D evaluation module datasheet.

  • The transformer selection depends on the specific application requirements such as output power, voltage, and frequency. Texas Instruments provides a transformer selection guide in the UCC28050D datasheet, which can be used as a starting point. Additionally, the UCC28050D evaluation module datasheet provides a list of recommended transformers that can be used with the device.

  • The UCC28050D has an operating temperature range of -40°C to 125°C. However, the device can be operated at a higher temperature range with derating. It's recommended to consult the datasheet for the thermal derating curves to ensure reliable operation.

  • The UCC28050D has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values. Texas Instruments provides a detailed application note on implementing OVP with the UCC28050D.

  • The recommended input capacitor value is typically in the range of 1uF to 10uF, depending on the input voltage and current requirements. A low-ESR ceramic capacitor or a film capacitor is recommended due to their low equivalent series resistance (ESR) and high ripple current capability.
