APPLICATIONS INFORMATION
APPLICATION #1: Offline Converter Provides
5.0 V, 1.0 A Output for Small Electronic Equipment
ON Semiconductor’s NCP1000 series of offline converters
offers a low cost, high efficiency power source for low power,
electronic equipment. It 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.

This kit provides a 5.0 V, 1.0 A 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, and EMI filters are included on
both the input and output.
