KA7577D規(guī)格書詳情
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.
Features
? Low Stand-By Current
? Pulse by Pulse Current Limiting
? Over Voltage Protection
? Over Current Protection
? Integrated Thermal Shutdown Circuit
? Output Driver Current of ± 2A
? Totem pole Output
