NCP1060 Datasheet, PDF (1/30 Pages) ON Semiconductor – High-Voltage Switcher

NCP1060, NCP1063
High-Voltage Switcher for
Low Power Offline SMPS
The NCP106X products integrate a fixed frequency current mode
controller with a 700 V MOSFET. Available in a PDIP−7, SOIC−10 or
SOIC−16 package, the NCP106X 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 NCP106X is quiet by nature:
MARKING DIAGRAMS
during nominal load operation, the part switches at one of the available
7
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.
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 (A version).
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.
NCP106x can be seamlessly used both in non−isolated and in
isolated topologies.
