PMIC - AC DC Converters, Offline Switchers is known as secondary power conversion, which is commonly used to convert the AC primary to the DC secondary, or vice versa. In this category, the TFS757HG is a converging step-down switch in a thermally enhanced 14-pin 3x3 QFN package. It offers excellent performance with a wide input voltage range of 4V to 40V. The TFS757HG is suitable for automotives, industrial, and communication system applications.

The TFS757HG features a very efficient, high-frequency, discontinuous conduction mode synchronous buck switched converter referenced as TFS technology. The device switches at a peak current of up to 1.4A and up to 1MHz switching frequency. It operates on a regulated output down to 0.5V and 1.4A output current. The TFS757HG offers an adjustable current limit with a programmable soft-start time to protect the system from high inrush current.

The TFS757HG is an efficient solution for step-down power applications. It is ideal for battery pack, automotive, digital power and applications requiring very high efficiencies and as battery pack chargers. It provides a highly efficient power conversion with fast transient response and low quiescent current. The device is designed to protet against overvoltage and overcurrent situations.

The TFS757HG application field and working principle is simple. The input voltage is applied across the device input pins, and the converter outputs a regulated voltage. The output voltage is adjustable, allowing the user to tailor the output voltage to the exact requirements. The switching frequency and duty cycle of the device is programmed by an external resistor. When the input voltage drops, the device automatically enters the low power saving mode.

The device enters a burst mode operation when the load is lower than the current limit or when the output is out of regulation. The device then enters a very low quiescent current off-mode state. The device can be re-enabled by a logic control signal or when the output voltage is in regulation again. The device also offers excellent reverse voltage protection.

With its advanced features, the TFS757HG is an ideal solution for high power applications including automotive, industrial, and communication systems. The device is designed to offer high performance and robustness, making it the perfect choice for power sensitive applications. The device’s small size, low power consumption, and high frequency switching make it an ideal solution for battery powered applications.
