常見問題解答

What is LNK304G?

The LNK304G is a low-power, energy-efficient, integrated off-line switcher IC (integrated circuit) designed by Power Integrations. It is commonly used in AC-DC power supply applications for devices such as chargers, adapters, and LED lighting fixtures.

How Does LNK304G Work?

The LNK304G operates as a switch-mode power supply controller, providing regulation and control functions for converting AC input voltage to a stable DC output voltage. It utilizes primary-side regulation technology to simplify circuit design and improve efficiency. The IC incorporates protection features such as overvoltage protection and output short-circuit protection.

How Many Pins does LNK304G have and What are the Functions of the Pinout Configuration?

The LNK304G is available in a 7-pin PDIP (Plastic Dual In-line Package) or SOP-7 (Small Outline Package) package. The pinout configuration typically includes:

  • VDD: IC power supply pin.
  • FB: Feedback pin for output voltage regulation.
  • BP / BPI: Bulk or Bulk Plus Input pin for connecting to the bulk input capacitor.
  • GND: Ground pin for the IC.
  • VCC: Supply voltage pin for the internal control circuitry.
  • EN / ENABLE: Enable pin for turning the IC on or off.
  • V:AC: AC input voltage pin for high-voltage applications.

What are the Pros and Cons of LNK304G?

Pros:

  • Low Power Consumption: Operates with high energy efficiency, suitable for power-conscious applications.
  • Integrated Protections: Includes built-in protection features for safe and reliable operation.
  • Compact Design: Available in small package options for space-saving designs.
  • Cost-Effective: Offers cost advantages for power supply designs.
  • Primary-Side Regulation: Simplifies circuit design and reduces component count.

Cons:

  • Application Specific: Primarily designed for low-power, offline switch-mode power supplies.
  • External Components: May require additional external components for specific applications or features.
  • Limited Voltage and Current Ratings: The IC may have limitations on maximum voltage and current handling capabilities.

Are There Any Equivalents/Alternatives to LNK304G for Recommendation?

  • Alternatives to the LNK304G include the FSD210 from Fairchild Semiconductor and the TOPSwitch series from Power Integrations.
  • Comparable ICs to the LNK304G are the TEA1533 from NXP Semiconductors and the TNY278 from Power Integrations.
