The modern electronics industry is characterised by a diverse range of markets and applications, requiring integrated DC-DC converters to meet conditions from the most demanding DC power requirements to the most sensitive environments.The PT6404D converter is an integrated power solution from Performance Technologies for increasing the efficiency of DC-DC applications. It features low input voltage range, excellent line and load regulation, and provides a wide range of power conversion capabilities. The PT6404D offers excellent performance with a high switching frequency, making it suitable for a wide range of applications such as energy storage systems, industrial and automotive.

Applications

The PT6404D converter is suited for a wide range of applications, including energy storage systems, automotive, industrial and development tools. In energy storage system applications, the PT6404D can provide efficient power management from batteries, converting high input voltage down to the output voltage requested. The device is well-suited for automotive applications as it provides complete power conversion from the on-board power supply for up to 14 separate loads using the integrated synchronous rectifiers.The PT6404D is also well-suited for the industrial sector, where it is often used for microinverters, providing a conversion from the 48 Vdc input power to a large number of string outputs, with up to 5.1 Vdc range. The device also can be used as a development tool, providing controlled Voltage to develop target boards.

Working Principle

The PT6404D is a dc-dc converter designed to operate over a wide input voltage range, from 9 Vdc to 48 Vdc, producing outputs from 0.8 Vdc to 5.1 Vdc. The device operates in a synchronous buck topology, using the integrated synchronous rectifiers to provide high efficiency over the complete range of input and output voltages.The PT6404D operates using a switching frequency of up to 800 kHz, which allows for a variety of input and output voltages. The device combines two switched modes, burst mode and constant off-time switching, allowing for efficient operation with low input current in any of the modes.When operating in constant off-time mode, the PT6404D switches at a fixed frequency, depending on the ratio of the input and output voltages. The device also supports phase skip mode which allows the converter to operate at higher frequencies, reducing the switching losses and improving overall efficiency.

Conclusion

The PT6404D is an integrated power solution, providing DC-DC conversion with high efficiency over a wide input voltage range and a variety of output voltages. It features excellent line and load regulation, and is well-suited for a variety of applications, from energy storage systems to industrial and automotive use. The device is designed to operate in both constant off-time and burst mode, supporting phase skip mode to improve efficiency, and is capable of operating up to 800 kHz.
