82472C Frequently Asked Questions (FAQ)
-
Murata recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
-
To ensure reliable start-up, ensure that the input voltage rises monotonically and that the input capacitor is properly sized to handle the inrush current. Also, ensure that the output voltage is properly decoupled to prevent oscillations.
-
The maximum allowable output capacitance for the 82472C is 100uF. Exceeding this value may cause instability or oscillations.
-
The 82472C is rated for operation up to 85°C ambient temperature. However, derating may be necessary for high-temperature applications. Consult the datasheet for derating curves and guidelines.
-
To troubleshoot issues with the 82472C, check the input voltage, output voltage, and output current. Verify that the input and output capacitors are properly sized and that the PCB layout is correct. Consult the datasheet and application notes for additional guidance.
