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 good airflow around the device and avoid blocking the thermal pad with other components or copper traces.
Although the datasheet doesn't specify a maximum voltage for the EN pin, Torex recommends keeping it within the VCC range (i.e., 2.5V to 5.5V) to ensure proper operation and prevent damage to the device.
While the XCL219B103FR-G is rated for operation up to 105°C, Torex recommends derating the output current and voltage according to the temperature derating curve provided in the datasheet to ensure reliable operation.
Torex provides a troubleshooting guide in their application note AN-103, which covers common issues and their solutions, including checking for proper power sequencing, decoupling, and layout.
