DC-DC Converters

DC-DC converters are electric devices used to convert a DC voltage to another DC voltage with a different amplitude. This type of converter has a wide range of applications, including powering small electronic devices such as processors and cell phones, as well as providing power to larger battery banks or power systems. The most common type of DC-DC converter is known as a buck-boost converter, which is capable of increasing or decreasing the voltage of a DC signal.

The PT6724N is a type of integrated DC-DC converter that was designed specifically for high-current, wide-input range applications. It is capable of providing up to 6.7A of output current, and can accept input voltages between 6V and 24V. The PT6724N is also designed to be highly efficient, with an efficiency of up to 94%.

Application Field

The PT6724N is a robust DC-DC converter, and can be used in many different applications. It is commonly used in automotive applications where space is limited, such as for powering infotainment systems or vehicle lighting. The wide input voltage range and high efficiency of the PT6724N make it particularly well suited for automotive applications.

The PT6724N is also used in industrial and commercial applications, such as distributed power systems and renewable energy systems. The wide input voltage range and high efficiency of the converter make it well suited for use in demanding environments, as the converter can operate reliably under fluctuating conditions.

Working Principle

The PT6724N is a buck-boost DC-DC converter. This type of converter uses an inductor to filter and store energy, while switches are used to control the direction of current flow through the inductor. This type of converter is capable of regulating both step-up and step-down conversions.

When input voltage is higher than output voltage, the converter will act as a step-down or buck converter. In this mode, the internal switches will be arranged in a configuration where current flows from the input voltage, through the inductor, to the load. This configuration will allow the converter to lower the voltage from the input to the desired output voltage.

When the input voltage is lower than the output voltage, the converter will act as a step-up or boost converter. In this mode, the internal switches will be arranged in a configuration where current flows from the input voltage, through the inductor, to the output voltage. This configuration will allow the converter to increase the voltage from the input to the desired output voltage.

The PT6724N is a synchronous buck-boost converter, meaning it has two sets of switches that are controlled by an internal clock. This type of converter is more efficient than asynchronous converters as it can switch more quickly and accurately. Additionally, the PT6724N includes protection features such as UVLO and current limits, making it a robust and reliable converter.
