The LNK576DG-TL is a 3.5-A off-line or isolated-flyback switching regulator. It is capable of delivering 3.5 A at the output voltage range from 5.5V to 36V with a maximum range of power of up to 50W. The IC is designed with a quasirun-free pulse-width modulation (PWM) controller IC, operating at a frequency of 600 kHz. With an operating temperature range of -40°C to +125°C, the device may be used in extreme environments and with a wide range of loads.

The LNK576DG is widely used in a variety of applications, such as AC/DC power supplies, wireless power systems, LED driver systems and portable electronic devices. The device is also popular in automotive and industrial applications such as stepper motors, printers, motors, pumps and medical equipment. The applications include high frequency DC/DC converters, AC/DC power converters, DC/DC Buck Regulator, pulse-width modulation DC/DC converters, flyback converters, as well as DC/AC inverters.

The LNK576DG-TL is equipped with multiple programmable functions and protection features, making it an ideal choice for a variety of applications. It has an adjustable switch on-time control, pulse-by-pulse current limiting and thermal shutdown. The device can also be used with chip-enable or power-good signaling, and allows for soft-start or synchronization with an external clock. The device also includes a power-factor correction (PFC) and a programmable under-voltage lock-out (UVLO) to ensure high-efficiency operation.

The LNK576DG-TL is a Pulse-mode Control (PMC) with low-side N-channel MOSFET switch. This switch is controlled by the PWM controller core. The core is designed with proprietary algorithms and on-chip compensation networks to ensure its stability with a wide range of compensator components. Its output is capable of up to 8A loads. The fast turn-on and turn-off times of the MOSFET switch make it suitable for high frequency switching.

The LNK576DG-TL includes a regulated 5.5V linear regulator, allowing for a wide voltage range operation. The 5.5V linear regulator allows for a large voltage range between the supply voltage and the output voltage, offering current-mode operation which is reliable at high switching frequencies. The device also features a constant on-time control protocol which helps reduce EMI and ripple noise, while at the same time suppressing transients.

The LNK576DG-TL is also equipped with built-in diagnostic features which allow its performance to be monitored and faults to be identified quickly. These diagnostic features include: cycle-by-cycle current limiting, over-temperature shutdown, under-voltage lock-out, power-on reset, fault protection and output short-circuit protection.

The LNK576DG-TL is a high-performance, cost-effective solution for many applications. It has been designed with an advanced feature set and easy-to-use safety functions. Its PFC and UVLO functions, as well as its low-side MOSFET switch, make it an ideal choice for use in advanced AC/DC converter designs.
