常見問題解答
What is LNK362DN?
The LNK362DN is a member of the LinkSwitch-CV family of ICs from Power Integrations. It is a highly integrated, energy-efficient, off-line switcher IC designed for low power AC-DC power supplies. The LNK362DN is commonly used in applications such as chargers, adapters, LED lighting, and other low power offline applications.
How Does LNK362DN Work?
The LNK362DN operates by converting AC input voltage into a well-regulated DC output voltage. It utilizes primary-side control technology, which eliminates the need for an optocoupler and provides precise control of the output voltage and current. The IC also features auto-restart for fault and over-temperature protection.
How Many Pins does LNK362DN have and What are the Functions of the Pinout Configuration?
The LNK362DN is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- BP/AC: Bulk input capacitor pin or an input for the DC bus voltage.
- GND: Ground reference pin.
- CD: Current sense and cycle-by-cycle frequency set pin.
- FB: Feedback pin for output voltage regulation.
- EN/UV: Enable/undervoltage lockout and open-loop failure pin.
- RTN: Return path for control circuitry.
- D: Drain pin for power MOSFET.
- NC: No connect pin.
What are the Pros and Cons of LNK362DN?
Pros:
- High Integration: Provides a high level of integration, reducing external components and simplifying design.
- Primary-Side Control: Eliminates the need for an optocoupler, reducing cost and component count.
- Auto-Restart Protection: Offers protection against faults and over-temperature conditions.
- Energy Efficiency: Designed for high efficiency, contributing to energy-saving designs.
Cons:
- Power Limitation: Suitable for low power applications and may not be suitable for high-power designs.
- Complexity: Primary-side control requires careful consideration of feedback and loop compensation for stable operation.
- External Components: Additional external components might be required for specific applications or regulatory compliance.
Are There Any Equivalents/Alternatives to LNK362DN for Recommendation?
Alternatives to the LNK362DN include the TOP260YN from Power Integrations and the FSDL0165RN from Fairchild Semiconductor.
