onsemi NCV1063AD100R2G

The NCV106X products integrate a fixed frequency current mode controller with a 670 V MOSFET. Available in a SOIC−10 or SOIC−16 package, the NCV106X offer a high level of integration, including soft−start, frequency−jittering, short−circuit protection, skip−cycle, adjustable peak current set point, ramp compensation, and a Dynamic Self−Supply (eliminating the need for an auxiliary winding). Unlike other monolithic solutions, the NCV106X is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (60 kHz or 100 kHz). When the output power demand diminishes, the IC automatically enters frequency foldback mode and provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby consumption down to a no load condition. Protection features include: a timer to detect an overload or a short−circuit event, Overvoltage Protection with auto−recovery and AC input line voltage detection (A version). The ON proprietary integrated Over Power Protection (OPP) lets you harness the maximum delivered power without affecting your standby performance simply via external resistors. For improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to reduce input power consumption below 50 mW at high line. NCV106x can be seamlessly used both in non−isolated and in isolated topologies.
