TNY286KG datasheet by Power Integrations

TNY286KG Frequently Asked Questions (FAQs)

• What is the maximum output power that the TNY286KG can handle?
  The TNY286KG is a 6W offline switcher IC, and its maximum output power depends on the input voltage, output voltage, and other design parameters. However, as a general guideline, it can handle up to 6W of output power with a maximum current of 1.2A.
• How do I ensure the TNY286KG operates within its safe operating area (SOA)?
  To ensure the TNY286KG operates within its SOA, follow the guidelines in the datasheet for maximum voltage, current, and power dissipation. Also, make sure to provide adequate heat sinking, and consider using a thermal interface material to improve heat transfer.
• What is the purpose of the BYPASS pin, and how do I use it?
  The BYPASS pin is used to connect an external bypass capacitor to the internal voltage regulator. This helps to improve the power supply rejection ratio (PSRR) and reduce noise. Connect a 1-10uF ceramic capacitor between the BYPASS pin and the GND pin.
• How do I optimize the design for low standby power consumption?
  To minimize standby power consumption, ensure that the input voltage is as low as possible, and use a high-value resistor (e.g., 1MΩ) for the feedback network. Also, consider using a low-ESR output capacitor and optimizing the transformer design for low losses.
• What is the recommended layout and placement for the TNY286KG?
  Follow the recommended layout guidelines in the datasheet, keeping the IC close to the transformer and output capacitors. Ensure good thermal conduction by placing the IC on a solid copper plane, and use a ground plane to reduce EMI.
