Integrated OffLine
Switching Regulator
The NCP1000 through NCP1002 series of integrated switching
regulators, combine a fixed frequency PWM controller with an
integrated high voltage power switch circuit. This chip allows for
simple design and minimal parts count for very low cost applications
which utilize an ac input. This chip is designed to power a single ended
topology, typically a discontinuous mode flyback, with secondary side
sensing.
The internal high voltage switch circuit and startup circuit can
function in continuous operation over a wide range of inputs, from 85
Vac to 265 Vac, and thus can be used in any existing power system in
the world. Though inexpensive, these devices include a number of
features such as undervoltage lockout, overtemperature protection,
bandgap reference and leading edge blanking that make them an
excellent value.
