DC – DC converters dominate a large segment of the power conversion market. Understanding their working principle and their application will help you to identify the correct product for your application. The PT6408E series is a popular module in the DC – DC converter family, offering low-voltage input, high-efficiency, and high-current output.

The PT6408E is a non-isolation DC – DC converter that offers efficiency up to 96%. It comes with a wide input range, from 18V to 36V, and can output up to 15A. The device also includes safety features such as output current limitation, under voltage lockout, over voltage protection, and a thermal shutdown function. The device is available in a wide variety of packages, from surface mount to through-hole configurations.

The basic operating principle of the PT6408E is similar to that of other DC – DC converters. The input voltage is rectified and filtered by a diode bridge and a capacitor. Then, the voltage is fed into the feedback loop, and the power stage consists of a voltage regulator (either a buck or boost regulator) and a power MOSFET. The feedback loop controls the output voltage and allows the device to maintain regulation even with changing input and output voltages. The output voltage can be adjusted either through external resistors or through a dedicated shift pin.

The PT6408E series is a great choice for a variety of applications. Its wide range of input voltages and outputs make it suitable for automotive, industrial, and consumer applications. It can also be used in battery-powered applications, such as laptops and portable devices, as it provides high efficiency and low power loss. It is a great choice for applications that require a stable and reliable power supply.

In summary, the PT6408E is a non-isolated DC – DC converter that provides a low-voltage input, high-efficiency, and a high-current output. It is suitable for a wide range of applications, from automotive to consumer applications. The device is easy to use and configure and offers safety features such as output current limitation, over voltage protection, and thermal shutdown protection. It is therefore an ideal choice for many applications where a reliable power source is required.
