TNY288DG datasheet by Power Integrations

TNY288DG Frequently Asked Questions (FAQs)

• What is the maximum output power that can be achieved with the TNY288DG?
  The maximum output power of the TNY288DG depends on the input voltage, output voltage, and current. However, according to the datasheet, the maximum output power is typically around 24W with a 230VAC input and 12V output.
• How do I ensure the TNY288DG operates within its safe operating area (SOA)?
  To ensure the TNY288DG operates within its SOA, follow the guidelines in the datasheet for maximum input voltage, output current, and power dissipation. Additionally, ensure proper thermal management, such as using a heat sink, and follow the recommended PCB layout and component placement.
• What is the purpose of the BYPASS pin on the TNY288DG?
  The BYPASS pin is used to connect a bypass capacitor to the internal voltage regulator. This pin is used to improve the power supply rejection ratio (PSRR) and reduce the output voltage ripple.
• How do I select the right transformer for use with the TNY288DG?
  When selecting a transformer for use with the TNY288DG, consider the input voltage, output voltage, and power rating. Ensure the transformer's voltage rating, current rating, and turns ratio are compatible with the TNY288DG's specifications. Consult the datasheet and application notes for guidance.
• What is the recommended PCB layout and component placement for the TNY288DG?
  The recommended PCB layout and component placement for the TNY288DG can be found in the datasheet and application notes. Key considerations include keeping the input and output stages separate, using a ground plane, and placing components to minimize electromagnetic interference (EMI).
