LNK304P

The LNK304P is a part of a new generation of isolated, high voltage, low noise, energy efficient AC/DC converters, offline switchers. This device integrates a 700 V power MOSFET and opto-coupler with its own biases, over-voltage protection, under voltage protection and an adjustable cycle-by-cycle current limit circuit.

The LNK304P is ideally suited for offline critical AC/DC topologies such as buck, flyback, forward, and quasi-resonant converters. Its\' dual-mode control operation allows these designs to be synchronized to an external clock or to switch asynchronously. It\'s high levels of integration and embedded control enable more efficient and lower cost solutions.

The device works by providing active switching and pulse width modulation on the primary. It monitors the primary current level during the off-time interval and adjusts the turn-on period accordingly. The opto-coupler provides isolation between the primary and secondary, ensuring the safety of the system and protection of the load.

The LNK304P offers energy efficient operation during high temperature operation and an integrated soft start, which reduces start-up current and inrush spike. It also boasts full protection from short circuit, over voltage, under voltage and over temperature conditions, as well as a current limit for improved safety.

It also provides a high power density design which minimizes the overall system size and provides thermal protection against overloads, thus resulting in a more reliable system. The LNK304P is ideal in the design of power adapters, consumer electronics, and other high voltage AC/DC applications, where efficiency and cost are critical factors.

Overall, the LNK304P is an excellent choice for applications where high efficiency and low cost are important, such as in consumer electronics, adapters and other AC/DC applications. Its\' robust and integrated design provides improved reliability and reduced system size. It offers dual-mode control and has excellent transient protection, providing protection against short circuit, over voltage, under voltage and over temperature conditions. Additionally, the LNK304P provides soft start to reduce the inrush current, high power density and energy efficient operation over a wide temperature range.
