Off-Line PWM Controllers with Integrated Power MOSFET
STR-A6000 Series
Data Sheet
General Descriptions
The STR-A6000 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.
The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components.
Features • Current Mode Type PWM Control • Brown-In and Brown-Out function • Auto Standby Function
No Load Power Consumption < 25mW
• Operation Mode
Normal Operation ---------------------------- PWM Mode Standby --------------------------- Burst Oscillation Mode

* The output power is actual continues power that is measured at 50 °C ambient. The peak output power can be 120 to 140 % of the value stated here. Core size, ON Duty, and thermal design affect the output power. It may be less than the value stated here.
Applications • Low power AC/DC adapter • White goods • Auxiliary power supply • OA, AV and industrial equipment
