Overview

The SY50583 is a high performance controller with constant current and constant voltage. It integrates a 700V MOSFET to decrease physical volume. In order to reduce the switching losses and improve EMI performance, Quasi-Resonant switching mode is applied, which means to turn on the power MOSFET at valley of drain voltage; the start up current of SY50583 is rather small (15μA typically) to reduce the standby power loss further; the maximum switching frequency is clamped to 45kHz to reduce switching losses and improve EMI performance when the converter is operated at light load condition. SY50583 provides reliable protections such as Short Circuit Protection (SCP), Over Voltage Protection (OVP), Over Temperature Protection (OTP), etc. SY50583 is available with SO8 package.
