UCC28070PWR Frequently Asked Questions (FAQ)
-
A good PCB layout for the UCC28070PWR involves keeping the high-frequency components (such as the switching FETs and diodes) close together, using a solid ground plane, and minimizing the length of the high-current paths. TI provides a recommended layout in the datasheet and application notes.
-
The inductor value depends on the output voltage, input voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. You can also use TI's online inductor selection tool or consult with a TI FAE for guidance.
-
The maximum ambient temperature for the UCC28070PWR is 85°C. However, the device can operate at higher temperatures with derating. Consult the datasheet for the thermal derating curve.
-
Yes, the UCC28070PWR can be used in a synchronous rectification topology. However, you'll need to ensure that the device is properly configured and the synchronous rectifier FET is properly sized to handle the reverse recovery current.
-
To troubleshoot oscillations or instability, check the PCB layout, component selection, and compensation network. Ensure that the compensation network is properly designed and the device is operating within its stable operating region. Consult the datasheet and application notes for guidance.
