特点：

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
