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

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.
