DC-DC converters are an important component of any electrical system, providing the necessary power and the ability to change voltage up or down. The PT78NR103H is a high-frequency, non-isolated DC/DC converter that provides a step-down output voltage from an input voltage of up to 24V. Its small size, excellent efficiency and accurate regulation make it an ideal choice for a cost-effective, reliable power supply solution for many applications.

The PT78NR103H DC/DC converter uses a synchronous rectification technique, which uses MOSFET switches in place of the traditional diodes used in rectifiers. This removes the power loss associated with diode conduction and ensures an efficient, high-power conversion. PWM control is used to regulate the output voltage, and a selectable voltage trim range provides various output-voltage settings. The current limit is also preset at a high level, ensuring reliable operation even when the output is short-circuited for extended periods.

The PT78NR103H converter also features a compact size, making it suitable for space-restricted applications. It has a wide input voltage range and can supply up to 7.8A of current, making it an ideal choice for a wide range of power-supply applications. With its low output ripple, low external part count and wide input and output voltage ranges, it is also well-suited for powering high-temperature applications.

The PT78NR103H offers many other features to meet the needs of a wide range of applications. It includes an on/off control, an over-temperature protection system and over-current protection. The converter has a wide operating temperature range from -40°C to 100°C. It is highly efficient, with a typical efficiency of 90% and allows for up to 93% efficiency at full load. It is also compliant with most of the safety approvals, such as UL, CSA and CE.

The PT78NR103H converter is an ideal choice for applications requiring high power density, cost-effectiveness, efficiency and reliability. It can be used in many applications including communications systems, industrial equipment and throughout the automotive industry. Its accuracy in voltage regulation, coupled with its high efficiency and wide temperature range, make it a great choice for power-supply designs in these various applications.
