PTH12040WAS datasheet by Texas Instruments

PTH12040WAS Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the PTH12040WAS?
  The maximum operating temperature range for the PTH12040WAS is -40°C to 125°C, as specified in the datasheet. However, it's recommended to derate the output power above 85°C to ensure reliable operation.
• How do I ensure the PTH12040WAS meets the required safety standards for my application?
  The PTH12040WAS meets various safety standards, including UL60950-1, IEC60950-1, and EN60950-1. To ensure compliance, follow the recommended layout and component selection guidelines provided in the datasheet and application notes.
• What is the recommended input capacitor value and type for the PTH12040WAS?
  The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 50V or higher. A low-ESR ceramic or film capacitor is recommended, such as the X5R or X7R dielectric type.
• How do I optimize the output voltage ripple and noise for my application?
  To optimize output voltage ripple and noise, use a combination of output capacitors with different values and types, such as ceramic, film, and electrolytic capacitors. The datasheet provides guidance on output capacitor selection and placement.
• What is the maximum output current derating for the PTH12040WAS at high temperatures?
  The maximum output current derating for the PTH12040WAS at high temperatures is approximately 1.5% per degree Celsius above 85°C. This means that for every degree above 85°C, the maximum output current should be reduced by 1.5% to ensure reliable operation.
