Application Note

Description

The STR6A100MV/HVD series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.
The operating mode of the IC automatically changes to green-mode or burst oscillation mode according to load in order to improve the all load efficiency. The product achieves high cost-performance power supply systems with few external components.

Application

● White Goods
● Office Automation Equipment
● Audio Visual Equipment
● Industrial Equipment
● Other Switched-Mode Power Supply

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
● Soft Start Function
● Adjustable Standby Operating Point
    No Load Power Consumption < 15 mW
● Operation Mode
    Fixed Frequency, 100 kHz
    Green-Mode, 25 kHz to 100 kHz
    Burst Oscillation Mode
● Random Switching Function
● Slope Compensation Function
● Leading Edge Blanking Function
● Bias Assist Function
● Protections
    Overcurrent Protection (OCP): Pulse-by-Pulse
    Overload Protection with Timer (OLP): Auto-restart
    Overvoltage Protection (OVP): Auto-restart
    Thermal Shutdown (TSD): Auto-restart
