STRW6251

 

 

Features

 Current-Mode Type PWM Control

 PWM with Jittering Function

The function reduces the EMI noise and enables simplified (low-cost) EMI filters.

The jittering period is adjustable by an external capacitor.

 Auto-Standby Function

The burst-oscillation enables the low standby power.

Input Power PIN < 100mW at no load

 Built-in Startup Circuit, enabling low power consumption

 Overcurrent Protection (OCP) with Built-in Input Compensation Circuit

The function has less AC input voltage dependency.

 Overload Protection (OLP) with Built-in Delay Timer ( the delay time is adjustable by an external capacitor)

 External Latch Protection (ELP)

The function enables the latch shutdown by external signal.

 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
