Torex provides a recommended PCB layout in their application note AN-104, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
Torex recommends using a thermal pad or thermal via under the IC to improve heat dissipation. Additionally, ensure that the PCB has adequate thermal conductivity and that the device is not exposed to high ambient temperatures or hot air flows.
Although the datasheet doesn't specify a maximum voltage for the EN pin, it's recommended to keep it within the VCC voltage range (1.7V to 5.5V) to ensure proper operation and prevent damage to the device.
While the XC9265A3314R-G is rated for operation up to 105°C, it's essential to consider the device's power dissipation, thermal management, and potential derating when operating in high-temperature environments. Consult with Torex or a thermal expert for specific guidance.
Start by verifying the power supply voltage, checking for proper PCB layout and thermal management, and ensuring that the device is not exposed to excessive noise or EMI. If issues persist, consult Torex's application notes and technical support resources or seek assistance from a qualified engineer.
