Murata recommends a PCB layout with a solid ground plane and a thermal relief pattern under the device to ensure good thermal conductivity. A minimum of 2 oz copper thickness is recommended.
To ensure reliable start-up, Murata recommends using a soft-start circuit to limit the inrush current and a voltage supervisor to monitor the output voltage. Additionally, a sufficient input capacitance should be used to filter out input voltage noise.
The maximum allowed capacitance on the output of the converter is 220uF. Exceeding this value may cause instability or oscillation in the converter.
The 26180C is rated for operation up to 85°C ambient temperature. However, derating of the output power may be necessary for high-temperature operation. Consult the datasheet for derating curves and thermal management guidelines.
To troubleshoot issues with the output voltage regulation, check the input voltage, output load, and feedback resistors for correctness. Also, verify that the output voltage sense lines are properly connected and not noisy. Consult the datasheet for a detailed troubleshooting guide.
