Description

ON Semiconductor's NCP1000 series of offline converters offers a low cost, high efficiency power source for low power, electronic equipment. AND8019 serves the same function as small, line frequency transformers, but with the added benefits of line and load regulation, transient suppression, reduction in weight, and operation across the universal input voltage range.

AND8019 provides a 5.0 volt, 1.0 amp output, which is derived from an input source of 85 to 265 VAC, and 50 Hz to 60 Hz. This range of input voltages will allow this circuit to function virtually anywhere in the world without modification. The output is regulated and current limited. Both common mode and differential mode EMI filtering are incorporated on the ac line
