PT4564C

The PT4564C is a high efficiency, synchronous step-down DC/DC converter of the switch mode power supply family. It offers an output voltage adjustable by an external voltage divider, up to a maximum of 24V and up to 8A. An internal high-speed current sense amplifier provides a load-current limit that improves system performance and compliance with international efficiency regulations. The PT4564C is suitable for a wide range of applications such as automotive, Ethernet switches and routers, storage and servers, medical instruments, power supplies and many others.

PT4564C belongs to a DC/DC converter which is an electronic circuit used to convert a source of direct current (DC) from one voltage level to another. It is a type of power electronic converter. Its main function is to convert a DC voltage from one level to another level which may be either lower or higher. As its name implies, it converts a DC supply voltage of one level, to a desired DC voltage of another level. As a result, DC/DC converters are often used in batteries, including those used in portable electronic devices. The DC/DC converter reduces battery weight and size by converting the higher voltage of a multiple cell battery to the required lower voltage.

The PT4564C includes an integrated high-efficiency synchronous step-down DC/DC controller, gate drivers and a few external components, allowing efficient operation at high-switch frequencies up to 1MHz. Its high-efficiency feature makes it feasible for use in systems with high-inrush current loads, such as server and computer system applications. The PT4564C includes synchronous rectification, and supports a wide range of external components for various topologies such as buck, boost, flyback or forward converter.

The PT4564C works by using a controller and a power stage to convert the input voltage to the output voltage level. The controller is the main part that determines the operation of the power stage. It is responsible for monitoring the input voltage and regulating the switching frequency of the power stage. The power stage is connected to the output and consists of an energy storage device, such as an inductor or transformer, connected to one or more MOSFETs, which allows for the conversion of the input voltage to the output voltage.

The PT4564C can be used in a variety of systems due to its flexibility. It can be used in high power applications such as DC/DC converters for laptop and desktop computer power supplies, as well as in high-efficiency applications such as cellular base station power converters and wireless networking gear. It is also suitable for industrial applications such as power supplies for industrial control systems and motor control applications.

The PT4564C is an elegant solution for a wide variety of DC/DC converter applications, offering high efficiency, superior performance and easy integration. Its flexibility and performance make it an ideal choice for a wide range of applications. By combining the PT4564C’s controller and an appropriate power stage, engineers can customize their system for the most demanding performance and high efficiency.
