KTB2140 Active Clamp Current-Mode PWM Controller

Kinetic Technologies KTB2140 Active Clamp Current-Mode PWM Controller integrates all the circuitry required to design a smart and efficient converter for PoE and telecom small and mid-powered applications. The Kinetic Technologies KTB2140 features a programmable oscillator for the switching frequency, adjustable slope compensation, dual low-side drivers with programmable dead time, programmable soft-start, soft-stop, programmable frequency dithering, and maximum duty limit. An internal high-voltage linear regulator allows the device to start up with a minimum number of external components. The controllers include dual low-side gate drivers mainly for active clamp forward applications. When the second driver is not used in low-power flyback converters, it can float. The KTB2140 device embeds a set of protections that enable the design of a self-protected converter and also targets high-efficiency conversion at a wide range of loads.
