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 start–up 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, over–temperature protection, bandgap reference and leading edge blanking that make them an excellent value.

The NCP100 is a precision low voltage shunt regulator that is programmable over a voltage range of 0.9V to 6.0V. This device features a guaranteed reference accuracy of ±1.7% at 25°C and ±2.6% over the entire temperature range of -40°C to 85°C. The NCP100 exhibits a sharp low current turn-on characteristic with a low dynamic impedance of 0.20Ω over an operating current range of 100μA to 20mA. These characteristics make this device an ideal replacement for zener diodes in numerous application circuits that require a precise low voltage reference. When combined with an optocoupler, the NCP100 can be used as an error amplifier for controlling the feedback loop in isolated low output voltage (2.3V) switching power supplies. This device is available in an economical space saving TSOP-5 package.
