Discover the perfect solution for your high voltage DC-DC conversion needs with STMicroelectronics' exceptional range of converters. Designed specifically for industrial applications, these converters offer outstanding performance and ruggedness.
One of the standout features of these converters is their ability to handle input voltages of 60V or higher, ensuring reliable operation even in challenging industrial environments.
Choose from our versatile range of converters, available with or without integrated switches, providing you with the flexibility to meet your specific requirements. The integrated switch option simplifies your design process, while the non-integrated version allows for greater customization.
Operating at switching frequencies ranging from 100kHz to 2.2MHz, our converters deliver excellent efficiency and precise power distribution. This wide frequency range ensures optimal performance across diverse applications, enhancing overall system efficiency and minimizing power losses.
Equipped with integrated FETs, these converters can handle output currents of up to 3A, making them suitable for a wide range of applications such as industrial machinery, robotics, drones, power tools, solar inverters, UPS and many others.
To support your development process, we provide evaluation boards (ev-boards) for all our converter parts, enabling rapid prototyping and system testing. This allows you to validate the converters' performance and functionality in your specific application.
STMicroelectronics' high voltage DC-DC converters are designed to accommodate input rails from 12V to 48V, making them an ideal choice for various voltage systems. With their reliability, efficiency, and performance, they are the perfect fit for industrial applications and beyond.
