Part Number : STR-A6053M
Function : Off-Line PWM Controllers with Integrated Power MOSFET
Package : DIP 8 Pin Type
Maker : Sanken Electric co.,ltd.
Pinouts : 
Description :
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
• Random Switching Function
• Slope Compensation Function
• Leading Edge Blanking Function
