Introduction
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.
source providing lossless startup, and eliminating external
startup circuitry. In addition, the NCP1230 has a PFC_V
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
