TNY280GN datasheet by Power Integrations

TNY280GN Frequently Asked Questions (FAQs)

• What is the maximum output power of the TNY280GN?
  The maximum output power of the TNY280GN is 8W, but it can be derated based on the input voltage, output voltage, and ambient temperature.
• How do I ensure the TNY280GN operates within its safe operating area (SOA)?
  To ensure the TNY280GN operates within its SOA, follow the guidelines in the datasheet for input voltage, output voltage, output current, and ambient temperature. Also, make sure to provide adequate heat sinking and thermal management.
• What is the purpose of the BYPASS pin on the TNY280GN?
  The BYPASS pin is used to connect a bypass capacitor to the internal voltage regulator. This helps to reduce the noise and ripple on the internal voltage regulator output, ensuring stable operation of the IC.
• Can I use the TNY280GN in a design with a high-impedance output?
  Yes, the TNY280GN can be used in designs with high-impedance outputs, but it's essential to ensure that the output voltage and current are within the specified limits. Additionally, consider adding output filtering or snubbing to reduce electromagnetic interference (EMI).
• How do I optimize the transformer design for the TNY280GN?
  To optimize the transformer design, follow the guidelines in the datasheet for transformer turns ratio, magnetizing inductance, and leakage inductance. Also, consider using a transformer with a low core loss and a suitable core material.
