FAQs
What is LNK305DG?
The LNK305DG is a low-power, off-line switcher IC designed by Power Integrations. It is commonly used in AC-DC power supply applications for low-power products such as chargers, adapters, and LED lighting.
How Does LNK305DG Work?
The LNK305DG works by converting AC input voltage into low-voltage DC output through a process of power conversion and regulation. It utilizes a combination of control circuitry, high-voltage power MOSFET, and transformer to achieve efficient power conversion while maintaining safety and reliability.
How Many Pins does LNK305DG have and What are the Functions of the Pinout Configuration?
The LNK305DG is housed in a 7-pin eSIP (extended Small-Outline Integrated Circuit Package) package. The pinout configuration includes:
- VIN: Input voltage pin.
- GND: Ground pin.
- VOUT: Output voltage pin.
- FB: Feedback pin for controlling the output voltage.
- BP: By-pass pin for connection to an external capacitor.
- D: Drain pin for the internal power MOSFET.
