Микросхема STRA6079M DIP7, А6079М ШИМ контроллер, черный, 10x8x9

Микросхема STR-A6079M DIP7, мар-ка A6079M, ШИМ контроллер. ■General Descriptions The STR-A6000 series products are power ICs for switching power supplies, incorporating a power MOSFET and a current-mode type PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components. ■ Features Current-Mode Type PWM Control Built-in Random Switching Function The function reduces the EMI noise and enables a simplified (low-cost) EMI filter, by the slight- random-change of PMW frequency fOSC. Auto-Standby Function: The burst-oscillation enables the low standby power. Input Power PIN < 25mW at no load Built-in Startup Circuit, enabling low power consumption Brown-In / Brown-Out Function. The function enables the oscillation start/stop by externally rated input voltage and makes protections at low input voltage. Overcurrent Protection (OCP) with Built-in Input Compensation Circuit: The protection has less AC input voltage dependency. Overload Protection (OLP) with Built-in Delay Timer High Speed Latch Release Function The function releases the latch immediately at AC supply OFF, after the latch protection operation. Bias-Assist Function, reducing Operating VCC voltage drop The function improves the startup operation and makes a low VCC capacitor applicable. Leading Edge Blanking Function Slope Compensation Function Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET Various Protections Overcurrent Protection (OCP) - Pulse-by-Pulse Overload Protection (OLP) - Auto-Restart Overvoltage Protection (OVP) - Latch Shutdown Thermal Shutdown Protection (TSD) - Latch Shutdown ■ Applications Battery Chargers; Mobile Phones, Digital Cameras, Camcorders, Electric Shavers, Emergency/Inducement Lights etc. Standby Power Supplies; LCD-TVs, PDP-TVs, Desk-Top PCs, LBPs, Audio Eq
