آیسی STRA6059

آی سی A6059H یک
Power IC for PWM Type Switching Power Supply with Low Noise and Low Standby Power نوع dip و ۸ پایه می باشد.
این نوع آی سی ها به عنوان آی سی های سوییچ در بازار معروف هستند.
این آی سی ها از سری STR-A6000 می باشند.

■ 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
