The SY5956 is a LLC controller. With proprietary control, it achieves fast dynamic response and easy loop compensation parameters design. The peripheral devices count is greatly reduced to save BOM cost. To minimize the switching power loss, the adaptive zero voltage switching (ZVS) is adopted in every switching period. The features easier design, lower EMI, and higher efficiency. The SY5956 incorporates anti-capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or has a severe overload. This feature protects the MOSFET during abnormal. The SY5956 enters a controlled burst mode at light load to minimize the power consumption and tighten output regulation. The SY5956 provides rich protection features, including cycle by cycle OCP, Brown in/out, OLP, output OVP and OTP, improving converter design safety with minimal extra components.
