Torex provides a recommended PCB layout in their application note AN-104, which includes guidelines for component placement, thermal vias, and routing to minimize noise and ensure stable operation.
The output capacitor selection depends on the output voltage, output current, and desired stability. A general guideline is to use a low-ESR ceramic capacitor with a value between 1uF to 10uF. Torex recommends using a 2.2uF capacitor for most applications.
Although the datasheet specifies a maximum input voltage of 6.5V, it's recommended to limit the input voltage to 6.0V to ensure reliable operation and prevent damage to the internal circuitry.
The XC9268B75CPR-G is rated for operation up to 125°C, but it's essential to consider the derating curves and thermal management to ensure reliable operation. Torex provides thermal resistance data in the datasheet to help with thermal design.
Torex provides a troubleshooting guide in their application note AN-105, which covers common issues, diagnostic techniques, and corrective actions. Additionally, it's recommended to consult the datasheet and contact Torex's technical support for specific guidance.
