The NCP1072/NCP1075 products integrate a fixed frequency
current mode controller with a 700 V MOSFET. Available in a
PDIP−7 or SOT−223 package, the NCP1072/5 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 NCP1072/5 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.
