NCP1230
OPERATING DESCRIPTION
Introduction
The NCP1230 is a current mode controller which provides
a high level of integration by providing all the required
control logic, protection, and a PWM Drive Output into a
single chip which is ideal for low cost, medium to high
power off ? line application, such as notebook adapters,
battery chargers, set ? boxes, TV, and computer monitors.
The NCP1230 can be connected directly to a high voltage
source providing lossless startup, and eliminating external
startup circuitry. In addition, the NCP1230 has a PFC_V CC
output pin which provides the bias supply power for a Power
Factor Correction controller, or other logic. The NCP1230
has an event management scheme which disables the
PFC_V CC output during standby, and overload conditions.
High Voltage
PFC_V CC
As shown on the internal NCP1230 diagram, an internal
low impedance switch SW1 routes Pin 6 (V CC ) to Pin 1
when the power supply is operating under nominal load
conditions. The PFC_V CC signal is capable of delivering up
to 35 mA of continuous current for a PFC Controller, or
other logic.
Connecting the NCP1230 PFC_V CC output to a PFC
Controller chip is very straight forward, refer to the “Typical
Application Example” all that is generally required is a
small decoupling capacitor (0.1 m F).
