FAQs

What is LNK304PG?

The LNK304PG is a member of the LinkSwitch-TN family of integrated offline switchers designed by Power Integrations. It is a low-power AC-DC converter IC that provides primary-side regulation for non-isolated applications like chargers, adapters, and household appliances.

How Does LNK304PG Work?

The LNK304PG integrates a high-voltage power MOSFET, advanced primary side control, and safety features into a single IC. It operates by controlling the on-time of the power MOSFET based on the primary current, achieving accurate output voltage regulation without the need for an optocoupler or secondary-side feedback circuit.

How Many Pins does LNK304PG have and What are the Functions of the Pinout Configuration?

The LNK304PG is available in a 7-pin eSIP package. The pinout configuration includes:

BP/M: Brownout protection and frequency setting pin.
FB: Feedback pin for output voltage regulation.
DC: Drain (output) pin of the internal power MOSFET.
DF: Drain (output) pin for external MOSFET with current limit.
RTN: Return pin for drain and bias currents.
BP/X: Brownout protection and frequency setting pin.
D: Drain (output) pin of the internal power MOSFET.

What are the Pros and Cons of LNK304PG?

Pros:

Primary-Side Regulation: Eliminates the need for an optocoupler and secondary-side feedback circuit.
Integrated Design: Combines power MOSFET and control circuitry in a single package for simplicity.
Low Component Count: Reduces external components and overall bill of materials.
Efficiency: Offers high efficiency performance for low-power applications.
Reliability: Includes features like thermal shutdown and auto-restart for system protection.

Cons:

Power Limitations: Designed for low-power applications and may not be suitable for high-power systems.
Design Complexity: Requires careful consideration of layout and thermal management for optimal performance.
