Off-Line PWM Controllers
Description
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
