SSL21082AT/1,118 datasheet by NXP Semiconductors

SSL21082AT/1,118 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  NXP provides a recommended PCB layout in the application note AN11542, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
• How do I select the correct input capacitor for the SSL21082AT/1,118?
  The input capacitor selection depends on the input voltage, current, and frequency. NXP recommends using a low-ESR capacitor with a value between 4.7uF to 10uF, and a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN11542 for more details.
• What is the maximum allowed voltage drop across the internal switch?
  The maximum allowed voltage drop across the internal switch is typically around 0.5V to 1V, depending on the specific application and operating conditions. Exceeding this voltage drop may lead to reduced efficiency, increased heat generation, or even device failure.
• How do I ensure electromagnetic compatibility (EMC) with the SSL21082AT/1,118?
  To ensure EMC, follow the guidelines in the application note AN11542, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and/or a ferrite bead to filter out electromagnetic interference.
• What is the recommended operating temperature range for the SSL21082AT/1,118?
  The recommended operating temperature range for the SSL21082AT/1,118 is -40°C to +125°C. However, the device can operate up to +150°C for short periods during startup or fault conditions. Refer to the datasheet for more information on thermal specifications.
