UC3879DW Frequently Asked Questions (FAQ)
-
The recommended input capacitor value is 10uF to 22uF, with a voltage rating of at least 25V. This ensures stable operation and reduces noise.
-
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, and then adjust based on the specific application requirements.
-
The UC3879DW can deliver up to 3A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions. It's essential to check the thermal derating curves in the datasheet to ensure reliable operation.
-
The UC3879DW has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output and the GND pin. The IC will shut down if the current exceeds the threshold set by the sense resistor value.
-
The EN pin is used to enable or disable the converter. When the EN pin is high, the converter is enabled, and when it's low, the converter is disabled. This pin can be used to implement power sequencing or to turn off the converter during standby modes.
