Beschreibung

The STR4A100 series are power ICs for switchingpower supplies, incorporating a sense MOSFET and acurrent mode PWM controller IC.The low standby power is accomplished by theautomatic switching between the PWM operation innormal operation and the burst-oscillation under lightload conditions. The product achieves highcost-performance power supply systems with fewexternal components.
