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
1. Current Mode Type PWM Control
2. Brown-In and Brown-Out function
3. Auto Standby Function
4. Random Switching Function
5. Slope Compensation Function
6. Leading Edge Blanking Function
7. Bias Assist Function
Applications
1. Low power AC/DC adapter
2. White goods
3. Auxiliary power supply
4. OA, AV and industrial equipment
