The SY2A58720 is a 500mA, 3.3V~5V, push-pull transformer driver, designed to provide a simple solution for isolated power supplies. The IC contains the carefully designed oscillating and driving circuit to provide precise complementary signals for two N-channel MOSFETs. The IC includes a soft-start feature that prevents high inrush current during power up. Its internal protection features include current limiting, under-voltage lockout and thermal shutdown. The SY2A58720 is available in a small 5-pin SOT-23 package and qualified with AEC-Q100.
