FAQs
What is LNK306G?
The LNK306G is a low-power off-line switcher IC designed by Power Integrations. It is specifically tailored for low-power AC/DC power supplies such as chargers, adapters, and auxiliary supplies. The device integrates a 700 V power MOSFET, oscillator, simple ON/OFF control, and a high-voltage startup circuit into a single package, providing a compact and efficient solution for offline power conversion.
How Does LNK306G Work?
The LNK306G operates by converting AC input voltage into a regulated DC output voltage using a switching power conversion technique. It utilizes primary side regulation, eliminating the need for an optocoupler and secondary feedback circuitry. The device features cycle-by-cycle current limit, hysteretic thermal shutdown, and frequency jittering for enhanced performance and robustness.
How Many Pins does LNK306G have and What are the Functions of the Pinout Configuration?
The LNK306G is available in a compact 7-pin eSIP (extended Small-Outline Integrated Circuit Package) package. The pinout configuration includes:
- BP, FB: BYPASS and FEEDBACK pins for providing feedback and control of the output voltage.
- SD, GND: Shutdown and ground pins for control and reference.
- Drain: MOSFET drain pin for switching the primary side of the transformer.
- Vin: Input voltage pin.
- Vout: Output voltage pin.
What are the Pros and Cons of LNK306G?
Pros:
- Integration: Integrates a 700 V power MOSFET, oscillator, and control circuitry, reducing external component count.
- Efficiency: Provides high efficiency and low standby power consumption, making it suitable for energy-efficient designs.
- Robustness: Features cycle-by-cycle current limit, thermal shutdown, and frequency jittering for enhanced reliability.
- Cost-Effective: Offers a cost-effective solution for low-power offline power supplies.
- Compact Package: The compact eSIP package enables space-efficient designs.
Cons:
- Power Limitation: Designed for low-power applications and may not be suitable for high-power systems.
