DC–DC converters are power supplies that convert a direct current (DC) input voltage to a higher or lower, DC output voltage. The PT5027H is a fault-protected full-resonant zero-voltage switching (ZVS) converter operating at high frequency (up to 30MHz).

The PT5027H switches both the input source and the output to control the voltage level, making it ideal for applications requiring high accuracy, efficiency and power delivery. Input voltage range of the PT5027H is 4.5V to 18V, while the output voltage range is 4.5V to 17.5V. Its operating frequency can be set between 5MHz and 30MHz with an external resistor, allowing the designer to choose the proper operating frequency to optimize the performance according to the load. It is a non-isolated converter working in an open-loop mode.

Application fields and working principles of PT5027H

Application Fields:

The PT5027H provides efficient power conversion and protection in a wide range of applications such as automated testing, industrial controls, motor drivers, LED drivers, battery-powered systems, and portable medical equipment. It can also be used in automotive, telecommunications, and portable devices.

Working Principle:

The PT5027H is a fault-protected, full-resonant ZVS DC-DC converter operating at high frequency. It works in a two-stage topology with one switching circuit for each stage. In the first stage, the input source and the output voltage are switched to adjust the voltage level. In the second stage, two switching circuits operate together to regulate the output voltage. The oscillator operating frequency of the PT5027H is set by an external resistor and works in open-loop mode, so the output voltage is not regulated by feedback. The input over-voltage and output over-voltage protections are built into the converter and can be enabled/disabled through two enable pins.

The PT5027H’s high efficiency and power delivery make it suitable for a variety of applications. Its non-isolated topology reduces size and cost, while its wide input range and integrated protections make it an ideal solution for powering devices efficiently and safely.
