Kinetic Technologies Announces World’s first 100V Power Converter IC with Integrated 5kV Isolation

KTB1100: 7V-100V, 15W Flyback Converter with Integrated Feedback and Digital Isolator

SAN JOSE, CALIFORNIA, UNITED STATES, January 11, 2021 /EINPresswire.com/ -- Power management and video/audio interface leader, Kinetic Technologies, is expanding its power conversion product portfolio with the world’s first highly integrated, high voltage flyback converters utilizing secondary digital isolation feedback. The KTB1100 operates directly from a wide 7V to 100V input supply and integrates all the major components, bar the transformer and rectifier diode, to create a highly efficient 15W isolated flyback converter with typically 1% output accuracy.

“The KTB1100 allows design engineers to simplify and reduce the size of their design, by integrating many of the external components normally required in isolated flyback designs”, says, Jia Hu, Senior Director of ESIA Product Marketing at Kinetic. “Adding digital isolated feedback allows designers to achieve high output voltage accuracy and regulation, without an external opto-coupler, compared to equivalent PSR designs.”

The KTB1100 also reduces the BOM and solution size by integrating a robust, internally protected 150V, low 350mΩ resistance output switching MOSFET and achieves close to 88% peak efficiency. Current-mode, constant on-time control, with an adjustable switching frequency of 100kHz to 1MHz, is used for fast transient response as well as superior output voltage regulation. The device features an active-high enable pin that can be connected directly to the input supply (up to 100V) with a soft-start function to limit the in-rush current at start-up.

With 5kVRMS isolation (UL1577 compliance pending), the KTB1100 also features several protection functions including undervoltage lockout, overvoltage lockout, cycle-by-cycle current limiting, short circuit protection and thermal shutdown protection.

The KTB1100 is supplied in a lead-free, RoHS, green wide-bodied SOIC-16pin package and is rated over the -40 to +85OC ambient temperature range.

Key applications for the new KTB1100 include battery management system (BMS) in electrical vehicles, telecom and communications power systems, industrial PLCs, smart meters, PoE, bias supply for isolated DC-DC converters and low-power isolated power modules.

KTB1100 pre-production samples are available now. Visit Kinetic Technologies for more information.
