Kinetic Technologies KTB1100 15W Flyback Regulator

Kinetic Technologies KTB1100 15W Flyback Regulator is highly integrated with a power MOSFET switch, internal feedback, and an integrated digital isolator. The internal digital isolation eliminates the need to use an external optocoupler and results in a small total solution size. Furthermore, the KTB1100 operates over a wide input voltage range from 7V to 100V to support various applications. The Kinetic KTB1100 15W Flyback Regulator implements current-mode constant on-time (COT) control for fast transient response and superior output voltage regulation.

The KTB1100 provides an adjustable soft-start function to limit inrush current during start-up. The device employs integrated protection features, including input voltage UVLO, output overvoltage protection (OVP), cycle-by-cycle current limit, short-circuit protection, and thermal shutdown.

The KTB1100 is housed in a RoHS and Green compliant SOIC-16 package.
