Offline Converter Provides
5.0 Volt, 1.0 Amp Output for
Small Electronic Equipment
Prepared by: Alan Ball
ON Semiconductor
General Description
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 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.
Features
Output Well Regulated Over Changes in Line and Load
