The LNK460KG-TL is a single stage, low voltage AC/DC offline switcher integrated circuit (IC) designed and manufactured by Power Integrations. It is a member of the LinkSwitch-TN family, intended for off-line, non-isolated power supply applications. This device features low power loss, high power factor and active power factor correction (PFC). The LNK460KG-TL is offered in a small yet power dense 48-pin package, making it ideal for applications requiring relatively high power density.

The LNK460KG-TL is designed for applications in the fields of general lighting, LED lighting and LED lighting backlighting, such as LED bulbs and LED tube lights. In LED lighting, the LNK460KG-TL is employed as an LED driver. It regulates the output from an AC input to provide the necessary DC power for a lighting system.

The LNK460KG-TL operates by providing an active PFC stage with a fixed frequency line-side boost converter, followed by a quasi-resonant flyback controller with primary side regulation (PSR). This self-biased device is optimized for power factor correction, takes advantage of zero load standby, and provides 65% efficiency at a typical operating frequency of 100kHz.

The LNK460KG-TL has an AC/DC offline switcher driver diode and an AC input capacitor included in the design. It also provides improved EMI performance by using an APFCFET, soft switching technology with advanced burst mode operation, and external snubbers. Its features include constant power stage and line voltage/frequency detection capabilities, as well as short-circuit and output over voltage protection.

The LNK460KG-TL is also suitable for use in other LED lighting applications, such as LED lighting backlighting and LED screens, as well as LED displays, LED street lights and LED signs. Its features make it ideal for use in a range of commercial, industrial and residential LED lighting applications, and its small package size means it is perfect for use in confined spaces. In terms of performance, the LNK460KG-TL is capable of driving up to 6 x 18 watts of LEDs in series (supplying a total of 108 watts at 5 V output) and delivers greater than 0.8 PF when driving a 3.6 x 18 W LED array.

The LNK460KG-TL is a versatile LED driver IC that offers high performance, power-saving capabilities, and efficient operation. It can help reduce power consumption and increase the energy efficiency of LED lighting systems, which can ultimately help reduce energy costs and improve light quality. Additionally, the device is capable of providing effective protection against short-circuits, inrush current and over-voltage conditions. Finally, the LNK460KG-TL is RoHS compliant, making it a safe and reliable choice for LED lighting applications.
