常見問題解答
What is LNK616DG?
The LNK616DG is a member of the LinkSwitch-TN2 family of off-line switcher ICs designed by Power Integrations. It provides a highly integrated solution for low-power, isolated power supplies in a wide range of applications, including home appliances, industrial controls, and IoT devices.
How Does LNK616DG Work?
The LNK616DG operates as an off-line switcher IC, integrating a MOSFET, a multi-mode PWM controller, and a high-voltage power MOSFET driver into a single chip. It uses primary-side regulation to achieve accurate output voltage regulation without the need for an optocoupler or secondary-side feedback circuitry. The device also features energy-efficient design, cycle-by-cycle peak current limit, and thermal shutdown protection for enhanced safety and reliability.
How Many Pins does LNK616DG have and What are the Functions of the Pinout Configuration?
The LNK616DG is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- BP: Bypass Pin for the internal high-voltage current source.
- FB: Feedback Pin for connecting the primary-side feedback circuitry.
- EN/UV: Enable/Undervoltage Lockout Pin for controlling the device's operational state.
- RTN: Return Pin for internal control circuits and output ground connection.
- DC: Drain/Collector Pin for the internal power MOSFET.
- DM: Drain Monitor Pin for externally connecting to a bleeder resistor to discharge the input filter capacitor.
- DS: Drain Sense Pin for monitoring the drain (DS) voltage of the power MOSFET.
- NC: Not Connected Pin, which is not internally connected and can be left unconnected.
What are the Pros and Cons of LNK616DG?
Pros:
- Integration: Highly integrated design reduces external component count and overall system cost.
- Efficiency: Energy-efficient operation helps meet energy efficiency standards and regulations.
- Reliability: Features such as cycle-by-cycle peak current limit and thermal shutdown enhance reliability and safety.
Cons:
- Complexity: Primary-side regulation and high-voltage operation require careful PCB layout and component selection for optimal performance.
- No External Feedback: Limited flexibility in certain applications that may require secondary-side feedback for regulation.
Are There Any Equivalents/Alternatives to LNK616DG for Recommendation?
- The LNK305 from Power Integrations is a related off-line switcher IC suitable for low-power applications.
- Alternatives to the LNK616DG include the TNY180PN from Power Integrations and the FSEZ1317 from Fairchild Semiconductor.
