The TNY379GN is part of a family of integrated offline switchers that accepts an input voltage range from 85VAC to 305VAC. The switcher is a buck-boost architecture, providing outputs of regulated 5V at 1.5A minimum with less than 6mV load regulation. The TNY379GN is designed to provide high efficiency and low cost performance. The device features a tight load regulation (<6mV), power good status indicator and fault protection features.

TNY379GN is a member of the PMIC - AC DC Converters, Offline Switchers family of ICs. They are ideal places for engineers and designers to find the best solutions for their applications with a wide range of options available. TNY379GN offers excellent efficiency and offers a low cost solution with the high quality current limit circuit that is needed to maintain the desired load regulation.

The TNY379GN uses an active clamping technique to provide a positive output voltage swing to quickly reduce the duty cycle of the internal control loop. This provides excellent transient response and fast loop control, as well as a low cost solution with excellent efficiency characteristics. The TNY379GN also features low output voltage ripple and excellent line and load regulation which ensure that the system stays in regulation and is not affected by large input line changes or load transients.

In addition to the operating features provided by the device, the TNY379GN also features a PGOOD (power good) status indicator that indicates that the output voltage is within ±10% of the nominal value. This indicates that the device is operating properly and can be used for monitoring the power supply in the system. The device also offers a number of fault protection features including overvoltage, overcurrent, and open-loop protection.

The TNY379GN is a very useful IC for applications that require a high efficiency buck-boost switching power supply with excellent load regulation and an onboard PGOOD indicator for monitoring output. The TNY379GN is ideal for applications such as white goods, small motor drives, and consumer electronic products. The device is also suitable for use as a general purpose switch mode power supply in a variety of applications.
