STR-A6053M PDIP-08 DIP8 (Pin 6 Removed)

Off-Line PWM Controllers with Integrated Power MOSFET STR-A6000 Series

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.
