The LNK354GN-TL a power management integrated circuit (PMIC) designed foruse in applications such as offline AC-to-DC converter designs using flyback converter topologies. Itis available with a minimum output voltage rating of 5.4V and a maximum output current of 0.5A.The device is based on a proprietary technology named "Transformerless Switching", which enableshigh-power density and low-profile designs.

The working principle of the LNK354GN-TL is that it converts an AC voltage input to a DC voltage.It does so by combining a transformer, power switch, and rectification elements into a single chip.The device can be used as an offline switcher and is suitable for creating a low-profile and high-efficiencyAC-to-DC converter design.

The LNK354GN-TL uses a primary-side current-mode control system to regulate the output voltage,ensuring stable voltage regulation and good dynamic load response. This allows the device to operateat higher frequencies, leading to high system efficiency and small passive elements. It also supportsfeatures such as Pulse-Width Modulated (PWM) dimming and power factor correction (PFC), whichfurther improves the total efficiency of the system.

The LN354GN-TL is highly integrated, which makes it well-suited for applications where space is at apremium. It includes integrated components such as an MOSFET driver, boost diode, frequency-jitteringcircuit, short-circuit protection, thermal shutdown, and over-voltage protection. These features reduce thebill of materials count, enabling a compact, efficient design.

The LNK354GN-TL is an advanced and reliable PMIC for AC-to-DC conversion applications andoffline switcher designs. It supports advanced protection features for increased safety and reliability.The integrated components allow for easier design implementation, resulting in a low-costpower conversion solution.
