A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended.
Apply a conformal coating to the device and ensure the PCB is designed with a moisture-resistant finish. Additionally, follow proper storage and handling procedures to prevent moisture absorption.
The maximum allowable voltage on the input pins is 5.5V, exceeding which may cause permanent damage to the device.
The device is rated for operation up to 85°C, but derating is required for temperatures above 70°C. Consult the datasheet for specific derating guidelines.
Check the input voltage, ensure proper connections, and verify that the enable pin is properly biased. If issues persist, consult the datasheet or contact Vishay support for further assistance.
