Description
KA7577 is fixed frequency PWM controller and specially
designed for SMPS to get regulated DC voltage from AC
power supply. This integrated circuit has so fast rise and fall
output pulse that it can directly drive power transistor as well
as power MOSFET. This device features high speed and
high sensitive current limiting. Protection circuitry include
current limiting function against short and over current at
secondary side, owing to the integrated timertype-protection
circuit.
