LTS-4940AHR Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing thermal vias under the device, using a solid ground plane, and keeping the thermal path as short as possible. A minimum of 2oz copper thickness is recommended.
  • To ensure reliable operation in high-temperature environments, it is essential to follow the recommended derating curves, ensure good thermal management, and avoid exceeding the maximum junction temperature (Tj) of 150°C.
  • The LTS-4940AHR has built-in ESD protection, but it is still recommended to follow standard ESD handling procedures during assembly and testing. Additionally, using ESD protection devices such as TVS diodes can provide extra protection.
  • Yes, the LTS-4940AHR can be used in switching regulator applications, but it is essential to ensure that the device is operated within its safe operating area (SOA) and that the switching frequency is within the recommended range.
  • The recommended storage condition for the LTS-4940AHR is in a dry, cool place with a temperature range of -40°C to 30°C and humidity below 60%. The device should be stored in its original packaging or in a similar anti-static package.
