UC2879DW Frequently Asked Questions (FAQ)
-
TI recommends a 4-layer PCB with a solid ground plane, and placing the IC close to the input capacitors. Also, keep the high-frequency components (e.g., transformer, diodes) away from the low-frequency components (e.g., input capacitors, output filter).
-
Choose a transformer with a turns ratio that matches the input and output voltage requirements. Ensure the transformer's core material and design can handle the frequency and power requirements. TI recommends a transformer with a magnetizing inductance of at least 10 μH.
-
The UC2879DW can handle up to 100 W of output power, but this depends on the specific application, input voltage, and transformer design. Ensure the IC and surrounding components can handle the maximum output current and power.
-
Use an external current sense resistor (Rcs) to monitor the output current. The UC2879DW has a built-in overcurrent protection (OCP) circuit that can be triggered by an external signal. Set the OCP threshold by selecting the appropriate Rcs value.
-
The VCC pin powers the internal logic and control circuits. Power the UC2879DW with a 5 V to 15 V supply, and ensure the voltage is stable and regulated to prevent malfunction or damage.
