The STR3A251 is a power ICs for switching power supplies, incorporating a MOSFET and a current-mode pWM controller IC.
The products achieve low power consumption and low standby power by including a startup circuit and a standby function that automatically switch operation modes – pWM mode in normal operation and burst-oscillation mode under light-load conditions.
Well-equipped with protection functions, the products also enable power supply systems to be more cost-effective with only a few external components.
