DESCRIPTION
To enhance efficiency in all load ranges, the IC automatically shifts its operation to the green mode or burst oscillation mode, depending on the load.FEATURES
● Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF)● Current Mode Type PWM Control
● Brown-in and Brown-out Function
● No Load Power Consumption, PIN < 25mW
● Automatically changed operation mode in response to load conditions - Fixed switching frequency mode, 100 kHz (typ.) in normal operation. - Green mode, 25 kHz (typ.) to 100 kHz (typ.) in middle to light load. - Burst oscillation mode in light load.
● Random Switching Function
● Slope Compensation Function
● Leading Edge Blanking Function
● Bias Assist Function
● Protections - Two Types of Overcurrent Protection (OCP): Pulse-by-Pulse, built-in compensation circuit to minimize OCP point variation on AC input voltage - Overload Protection with timer (OLP): Ato restart - Overvoltage Protection (OVP): Latch shutdown - Thermal Shutdown (TSD): Latch shutdown Typical Application Package DIP8 Not to Scale.
