Tamura recommends a PCB layout with a solid ground plane, minimal track length, and a decoupling capacitor (e.g., 10nF) between the input and output pins to reduce noise and ensure stable operation.
To ensure reliable start-up and shutdown, Tamura recommends a soft-start circuit or a ramp-up/ramp-down control of the input voltage to prevent inrush currents and voltage spikes.
The maximum allowed capacitance on the output is 100uF. Exceeding this value may cause instability or oscillations in the converter.
The S22P025S05M2 is rated for operation up to 85°C ambient temperature. However, derating may be necessary for higher temperatures. Consult Tamura's application notes for guidance on high-temperature operation.
To troubleshoot output voltage regulation issues, check the input voltage, output load, and PCB layout. Ensure that the input voltage is within the specified range, the output load is within the recommended range, and the PCB layout follows Tamura's recommendations.
