onsemi NCP10672BD060R2G

The NCP1067X products integrate a fixed frequency current mode controller with a 700 V MOSFET. Available in a SOIC−7 package, the NCP1067X offer a high level of integration, including soft−start, frequency−jittering, short−circuit protection, skip−cycle, ramp compensation, and a Dynamic Self−Supply (eliminating the need for an auxiliary winding). During nominal load operation, the NCP1067X switches at one of the available frequencies (60 or 100 kHz). When the output power demand diminishes, the IC automatically enters into a skip mode to reduce the standby consumption down. Protection features include: a timer to detect an overload or a short−circuit event, Overvoltage Protection with auto−recovery. For improved standby performance, the connection of an auxiliary winding or supplying the IC from the output, stops the DSS operation and helps to reduce input power consumption below 25 mW at high line. NCP1067x can be seamlessly used both in non−isolated and in isolated topologies.
