PMIC - AC DC Converters, Offline Switchers, are critical components of modern power systems. The LNK363DN-TL is a high-efficiency, low-power, low-voltage dual-output, isolated offline switching regulator with a maximum output current of up to 2A. It is designed to provide an efficient and reliable solution for high-power, offline power systems.

The LNK363DN-TL operates in either of two modes: burst-mode operation or fixed-frequency pulse-width modulation (PWM) operation, providing a high degree of flexibility for applications requiring different modes of operation. In burst-mode, the operating frequency and duty cycle are automatically adjusted to maintain the desired load current. The PWM operation maintains a constant frequency and adjusts the switching duty cycle to maintain the load current. The adjustable output current limit, high efficiency and fast transient response, along with the low standby power consumption and low audible noise, makes the LNK363DN-TL an ideal choice for a wide range of offline applications.

The LNK363DN-TL can be used in a number of different applications, such as home and office lighting, computer power supplies, consumer appliances, telecom, and industrial equipment. With its adjustable output current limit, the LNK363DN-TL is also suitable for LED lighting applications, as it can be used to optimize the LED current while still ensuring a long LED life span.

The LNK363DN-TL features an integrated power switch, high-side current sense, current mode control, soft start, under voltage lockout, thermal shutdown, and over voltage protection. The power switch contains an output disconnect, fault indicating circuitry, and an integrated over current protection circuit. The high-side current sense feature allows optimized regulation accuracy due to the regulator\'s direct control of current. The current mode control provides excellent line and load regulation, as well as easy loop compensation. The soft start feature gradually ramps up the output voltage, ensuring a smooth transition from inactive to active operation.

The under voltage lockout feature prevents unwanted start-up due to input power drops, whereas the thermal shutdown feature protects against over-temperature conditions. The over voltage protection in the LNK363DN-TL prevents over voltage conditions due to unexpected hot plugging. The LNK363DN-TL also implements PWM/Burst-mode transition mode in which it transitions between PWM and Burst-mode operation as the load changes, allowing fast transient response and high efficiency across all load conditions.

In conclusion, the LNK363DN-TL is an ideal choice for a wide range of offline applications such as home and office lighting, computer power supplies, consumer appliances, telecom, and industrial equipment. With its adjustable output current limit, the LNK363DN-TL can also be used in LED lighting applications, making it a highly efficient and reliable solution for providing power to many different types of electronic devices.
