Overview: Automotive High-Voltage Switcher for Low Power Offline SMPS
NCV1060, NCV1063
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.
