FAQs
What is LNK304P?
The LNK304P is a low-power, off-line switcher IC designed by Power Integrations. It is commonly used in AC-DC power supplies for appliances, LED lighting, and other low-power applications. The IC incorporates a primary-side regulation (PSR) technique for simplified design and high efficiency.
How Does LNK304P Work?
The LNK304P works by integrating a high-voltage power MOSFET, control circuitry, and a current sense into a single IC. It utilizes the PSR technique to achieve accurate control of the output voltage without the need for an optocoupler or a secondary feedback circuit. The device operates in a discontinuous conduction mode (DCM) to minimize losses and maximize efficiency.
How Many Pins does LNK304P have and What are the Functions of the Pinout Configuration?
The LNK304P is housed in a 7-pin PDIP (Plastic Dual In-line Package) or SO-8 (Small Outline) package. The pinout configuration includes:
- BP/M: Brownout/maximum duty cycle or internal current limit pin.
- FB: Feedback voltage regulation pin.
- EN/UV: Enable/undervoltage lockout (UVLO) pin.
- BP/M: Brownout/maximum duty cycle or internal current limit pin.
- V: Input voltage pin.
- Drain: Drain (power) pin of the integrated MOSFET.
- NC: No connection pin.
What are the Pros and Cons of LNK304P?
Pros:
- Integrated Design: Combines multiple functions into a single IC, simplifying system design.
- Primary-Side Regulation: Eliminates the need for an optocoupler and secondary-side feedback circuitry, reducing component count and cost.
- Efficiency: Operates in DCM to achieve high efficiency and low standby power consumption.
- Compact Package: Available in space-saving PDIP or SO-8 packages for versatility in board designs.
Cons:
- Limited Power Range: Designed for low-power applications and may not be suitable for high-power systems.
- External Components: May require external components for specific protection or filtering requirements.
Are There Any Equivalents/Alternatives to LNK304P for Recommendation?
- The TNY274P from Power Integrations is a comparable off-line switcher IC with similar features.
- Alternatives to the LNK304P include the FSDM0265R from Fairchild Semiconductor and the TOP225Y from Power Integrations.
