DC-DC converters are used to convert and regulate electrical power. The PT78HT208H is a DC-DC converter designed for applications that require a high efficiency conversion from a regulated 8-16V DC input voltage to a controllable, adjustable 2.5V to 5V DC output voltage. It is commonly used in a variety of applications, from vehicle networks to industrial automation systems.

The PT78HT208H is part of a new series of DC-DC converters from Technocel, which share many common features. They are all small, efficient and capable of operating over a wide temperature range from -40C to +85C. They have a wide range of acceptable input voltage and deliver an adjustable output voltage suitable for many applications.

The PT78HT208H features a unique set of features that make it an ideal choice for applications with space constraints. It includes a non-isolated synchronous two-phase buck-boost design that allows for a higher output voltage than the input for applications that must step-down the voltage. It is also equipped with an embedded controller to provide intuitive over-temperature protection, current limiting and input undervoltage protection.

The PT78HT208H also has a lightweight, enclosed casing for improved EMC performance and reliability. It also has an adjustable soft-start function to reduce inrush current, a current limiting control circuit to limit the output current to the specified value and a push-pull output control circuit to maintain the adjustable output voltage.

The PT78HT208H is designed for use in industrial applications, as well as in consumer electronics such as laptops and cell phones. It is capable of delivering a wide range of output voltages with a high degree of accuracy and efficiency. Its wide acceptance range and adjustable output makes it a great choice for applications such as automotive networks, lighting systems, power systems and industrial automation.

The working principle of the PT78HT208H is based on the basic Buck-Boost design. In this design, two complete power conversion cycles are used to convert power. The buck-boost converter is based on the basic buck-boost topology of a dc-dc converter. The buck-boost converter is specifically designed to be used in wide input voltage range applications. It works on the concept of an inductor being used to store energy in the form of magnetic flux.

First, the input voltage is stepped down to the desired output voltage by the buck converter. Then, the same inductor is used to step up the voltage by the boost converter, resulting in the desired output voltage. The two cycles of conversion enable the converter to have a wide input voltage range and variable output voltage, making it suitable for a wide range of applications.

The PT78HT208H also offers a variety of important advantages. It is highly efficient, able to achieve over 94% efficiency at full load. It is also capable of operating over a wide temperature range, which makes it an ideal choice for industrial applications. It also benefits from a lightweight and small form factor that makes it easy to install and mount to walls or ceilings.

The overall working for the PT78HT208H is simple and effective. The input voltage is stepped down by the buck converter and then stepped up by the boost converter to the desired output voltage. It also offers a variety of features, including current limiting, over-temperature protection and adjustable output, that make it a great choice for a wide range of applications. Its versatile design and efficient operation make it an excellent choice for a wide range of applications.
