KTB1100 Datasheet Brief :15W Flyback Regulator with Digital Isolator Integrated Feedback
The KTB1100 employs current-mode constant on-time (COT) control for fast transient response as well as superior output voltage regulation. The device features an adjustable soft-start function to limit inrush current during start-up. The device has 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 available in RoHS and Green compliant SOIC-16 package.
