FAQs

What is LNK306P?

The LNK306P is a member of the LinkSwitch-XT family of integrated circuits designed by Power Integrations. It is a low-power, off-line switcher IC that incorporates a high-voltage power MOSFET and various control features into a single device. The LNK306P is commonly used in power supply applications, including chargers, adapters, and LED lighting.

How Does LNK306P Work?

The LNK306P works by providing a complete power conversion solution for off-line applications. It integrates a primary side regulated PWM controller, a high-voltage power MOSFET, frequency jittering, cycle-by-cycle current limit, and other control functions to deliver efficient and reliable power supply operation. The device utilizes flux-linkage technology to transfer energy across the isolation barrier of the IC, eliminating the need for an optocoupler or third winding for feedback.

How Many Pins does LNK306P have and What are the Functions of the Pinout Configuration?

The LNK306P is housed in a 7-lead PDIP (Plastic Dual In-Line Package) and 7-lead SMD package. The pinout configuration includes:

  • BP: Bypass Pin for internal high-voltage current source.
  • EN/UV: Enable / Undervoltage Lockout Pin for controlling the IC's operation.
  • FB: Feedback Pin for connection to the secondary side of the transformer or an optocoupler for regulation.
  • COM: The return path for the output current and control circuits.
  • D: Drain Pin of the integrated MOSFET to switch the primary winding of the transformer.
  • SR: Source Pin of the integrated MOSFET.
  • P: Power Pin for connection to an external resistor to set the peak switch current and for power dissipation.

What are the Pros and Cons of LNK306P?

Pros:

  • Integration: Combines a power MOSFET and control features into a single IC, simplifying the design of off-line power supplies.
  • Efficiency: Provides high efficiency and low standby power consumption.
  • Flux-Linkage Technology: Eliminates the need for an optocoupler or third winding for feedback, reducing component count and cost.
  • Safety: Includes various protection features such as line overvoltage protection and auto-restart for fault conditions.
  • Compact Package: Housed in a compact PDIP or SMD package for space-efficient designs.

Cons:

  • External Components: May require external components such as a transformer and output diode for power supply operation.
  • Thermal Considerations: Proper thermal design and heat sinking may be necessary for high power applications.
  • Application Complexity: Requires careful consideration of transformer design and feedback loop compensation for optimal performance.

Are There Any Equivalents/Alternatives to LNK306P for Recommendation?

  • The LNK303 from Power Integrations is a similar off-line switcher IC with slightly different features.
  • Alternatives to the LNK306P include the FSL126MR from ON Semiconductor and the NCP1252 from ON Semiconductor.
