Automotive High-Voltage
Switcher for Low Power
SMPS
The NCV107x products integrate a fixed frequency current mode
controller with a 670 V MOSFET. Available in a PDIP7 package, the
NCV107x offer a high level of integration, including softstart,
frequencyjittering, shortcircuit protection, skipcycle, a maximum
peak current set point, ramp compensation, and a Dynamic

SelfSupply (eliminating the need for an auxiliary winding).
Unlike other monolithic solutions, the NCV107x is quiet by nature:
during nominal load operation, the part switches at one of the available
frequencies (65, 100 or 130 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
shortcircuit event, Overvoltage Protection with autorecovery and
AC input line voltage detection.
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.
