ACTIVE
STR3A475HDL
Package : DIP8
RoHS : YES
The STR3A475HDL is a power IC for switching power supplies, incorporating a MOSFET and a current mode PWM controll 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.
