NCP1000

1. This device series contains ESD protection and exceeds the following tests: Pins 1−3: Human Body Model 2000 V per MIL−STD−883, Method 3015. Machine Model Method 200 V. Pins 4 and 5 are the HV start−up and the drain of the LDMOS device, rated only to the max rating of the part , or 700 V.
2. This device contains Latch−up protection and exceeds 200 mA per JEDEC Standard JESD78.

The NCP1000 through NCP1002 series of integrated switching regulators, combine a fixed frequency PWM controller with an integrated high voltage power switch circuit. This NCP1000 chip allows for simple design and minimal parts count for very low cost applications which utilize an ac input. This NCP1000 chip is designed to power a single ended topology, typically a discontinuous mode flyback, with secondary side sensing.

The NCP1000 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.
