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:
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.
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.

Function
The IC Ground
Powers the internal
circuitry
Ipeak set / Over
power limitation
This pin is connected to an external capacitor. The V
DD
includes an auto−recovery over voltage protection.
The current drown from the pin decreases Ipeak of the
primary winding. If resistive divider from the auxiliary
winding is connected to this pin it sets the OPP compen-
sation level (it diminishes the peak current.)
This is the inverting input of the trans conductance error
amplifier. It is normally connected to the switching power
supply output through a resistor divider.
The error amplifier output is available on this pin. The
network connected between this pin and ground adjusts
the regulation loop bandwidth. Also, by connecting an
opto−coupler to this pin, the peak current set point is
adjusted accordingly to the output power demand.
This un−connected pin ensures adequate creepage dis-
tance
