常見問題解答

What is TNY290KG-TL?

The TNY290KG-TL is a primary-side regulated (PSR) energy-efficient, off-line switcher IC (integrated circuit) designed by Power Integrations. It is ideal for low-power AC-DC applications such as power adapters, auxiliary power supplies, and home appliances.

How Does TNY290KG-TL Work?

The TNY290KG-TL utilizes a patented energy-efficient technology to provide accurate output voltage regulation without the need for an opto-coupler or secondary-side feedback circuitry. It incorporates a high-voltage power MOSFET and a controller to deliver high efficiency and precise output voltage regulation. The device operates in continuous conduction mode (CCM) for improved efficiency at light load conditions.

How Many Pins does TNY290KG-TL have and What are the Functions of the Pinout Configuration?

The TNY290KG-TL is housed in a 7-pin SMD (Surface Mount Device) package. The pinout configuration includes:

  • 1. BP/MNC: Brownout protection or multi-function pin.
  • 2. Drain: High-voltage drain pin for the power MOSFET.
  • 3. Sense: Voltage feedback sense pin for output voltage regulation.
  • 4. NC: Not connected or no connection pin.
  • 5. Source: Power return or source pin for the power MOSFET.
  • 6. Control: Control and fault detection pin.
  • 7. BP/MNC: Brownout protection or multi-function pin (second occurrence).

What are the Pros and Cons of TNY290KG-TL?

Pros:

  • Primary-Side Regulation: Eliminates the need for an opto-coupler and secondary-side feedback components, reducing system cost and complexity.
  • Energy Efficiency: Achieves high efficiency through patented energy-efficient technology, contributing to reduced power consumption and heat generation.
  • Compact Design: Compact SMD package for space-constrained applications.
  • Built-In Protection Features: Includes over-temperature, over-voltage, and auto-restart protection for enhanced system reliability.

Cons:

  • Output Power Limitation: The TNY290KG-TL is optimized for low-power applications and may not be suitable for high-power requirements.
  • Application Specific: Designed for specific AC-DC power applications and may not be suitable for all power conversion needs.
  • External Components: May require additional external components for input filtering and output rectification.

Are There Any Equivalents/Alternatives to TNY290KG-TL for Recommendation?

  • The TNY299KG-TL is a similar PSR switcher IC from Power Integrations with enhanced features.
  • Alternatives to the TNY290KG-TL include the FSL306LRN from Fairchild Semiconductor and the TOP256EN from Power Integrations.
