概述

Description

The LNK306GN-TL is a compact, integrated power supply solution from the LinkSwitch family, primarily designed for applications requiring a low-output voltage, such as LED drivers, consumer electronics, and battery chargers. It operates in a flyback configuration, enabling high efficiency and low standby power consumption.
Key features include a wide input voltage range, typically from 85 to 265 VAC, and an output power capability of up to 6 watts. It integrates a high-voltage power MOSFET and control circuitry, simplifying design and reducing component count. The device also includes built-in protections like overvoltage, overcurrent, and thermal shutdown to enhance reliability.
The LNK306GN-TL is particularly valued for its ease of use and minimal external components, making it suitable for space-constrained applications. Its ability to meet various energy efficiency standards makes it a popular choice in energy-conscious designs.

Features

The LNK306GN-TL is a highly integrated, low-power switcher IC designed for offline, low-voltage power supply applications. Key features include:
1. High Voltage Startup: It operates directly from the AC line without needing an external switch, simplifying design.
2. Built-in Switch: Integrated power MOSFET with a maximum output of 15W.
3. Frequency Modulation: Provides improved EMI performance and reduced transformer size.
4. Low Standby Power: Delivers energy efficiency with very low standby power consumption, meeting global energy regulations.
5. Short-Circuit Protection: Integrated features to protect against overload conditions.
6. Thermal Shutdown: Ensures device safety by shutting down in case of overheating.
7. Compact Package: Offered in an 8-pin SOIC package, facilitating space-saving designs.
The LNK306GN-TL is suitable for applications such as adapter and charger designs, LED drivers, and other low-power AC-DC applications.
