Description

The STR6A153MV 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 Supplies

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, 65 kHz
 Green-Mode, 25 kHz to 65 kHz
 Burst Oscillation Mode
・Random Switching Function
・Slope Compensation Function
・Leading Edge Blanking Function
・Bias Assist Function
・Protections
 Overcurrent Protection (OCP): Pulse-by-Pulse
