Part Number Description
Off-Line PWM Controllers
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 • Random Switching Function • Slope Compensation ...
