DC-DC converters are electronic devices that convert a direct current (DC) power supply to a different voltage DC power supply. One such device is the PT5028A from MicroPower Direct. The PT5028A is a low-profile, isolated, regulated DC-DC converter, capable of delivering up to 2 Amps of current.

The PT5028A is designed for applications where space is at a premium and the need for a wide input voltage range is essential. It features out-of-the-box adjustable output voltage settings from 1.8 V to 5.5 V, and an ultra-wide 4:1 input range from 6 V to 24 V, allowing it to provide a regulated, low ripple, output voltage to power up your sensitive electronic components with extreme reliability.

Working Principle

The PT5028A works on the principle of buck-boost converter. It takes a supplied DC voltage and converts it to a lower or higher DC voltage with the help of a switching mechanism and associated control circuitry. The basic buck-boost converter consists of an inductor, two switches and a diode. When the switch is opened, the stored energy in the inductor is used to supply the load. When the switch is closed, the current begins to increase, allowing the voltage on the load to increase. When the switch is opened again, the voltage on the load decreases, and the current through the inductor also decreases. This process is repeated periodically, resulting in a continuous current to the load.

Application Fields

The PT5028A is a feature-rich and cost-effective DC/DC converter, ideal for a wide range of applications. It is the perfect choice for various applications such as industrial, communications, medical, telecom, automotive and consumer electronics. It is an ideal solution for applications with limited space, requiring isolated DC-DC conversion with adjustable output voltage and wide input voltage range.

In industrial applications, the PT5028A ensures steady and reliable power supply for different types of automation equipment such as PLCs (Programmable Logic Controllers), controllers, sensors and motor drives. In telecom applications, the converter can be used for powering various telecom devices, such as line cards, modems, cellular base stations, and fiber optic systems.

The PT5028A is particularly well-suited for medical applications, as it features Medical Grade isolation, ensuring that no outside interference enters the system and no harmful noise or electromagnetic radiation is generated. In automotive applications, the converter is used for powering various electronic devices such as infotainment systems, sat-nav, dash displays, and much more.

Finally, in consumer electronics, the PT5028A is ideal for powering various types of imaging and display products such as TV sets, monitors, set-top boxes, and other consumer devices.

Conclusion

The PT5028A from MicroPower Direct is a low-profile, isolated, regulated DC-DC converter, capable of delivering up to 2 Amps of current. Its out-of-the-box adjustable output voltage settings allow for a wide range of applications, including industrial, communications, medical, telecom, automotive and consumer electronics. The PT5028A also features Medical Grade isolation, ensuring that no outside interference enters the system and no harmful noise or electromagnetic radiation is generated. All in all, it is an ideal solution for applications where space is at a premium and the need for a wide input voltage range and reliable power output is essential.
