MC44603, Mixed Frequency Mode GreenLine PWM Controller

Order this document by MC44603/D MC44603 Mixed Frequency Mode GreenLine™ PWM Controller: Fixed Frequency, Variable Frequency, Standby Mode The MC44603 is an enhanced high performance controller that is specifically designed for off line and dc to dc converter applications.

This device has the unique ability of automatically changing operating modes if the converter output is overloaded, unloaded, or shorted, offering the designer additional protection for increased syst

MC44603 Features

* when compared to conventional SMPS controllers. These features consist of a foldback facility for overload protection, a standby mode when the converter output is slightly loaded, a demagnetization detection for reduced switching stresses on transistor and diodes, and a high current totem pole outpu
