High-Voltage Switcher for
Low Power Offline SMPS
The NCP107x products integrate a fixed frequency current mode

controller with a 700 V MOSFET. Available in a PDIP−7 or SOT−223
package, the NCP107x offer a high level of integration, including
soft−start, frequency−jittering, short−circuit protection, skip−cycle, a

maximum peak current set point, ramp compensation, and a Dynamic
Self−Supply (eliminating the need for an auxiliary winding).
Unlike other monolithic solutions, the NCP107x 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

short−circuit event, Overvoltage Protection with auto−recovery 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.
