DESCRIPTION
The IP5560 is a control circuit for use in switched mode power supplies. This single monolithic chip incorporates all the
control and supervisory (protection) functions required in switched mode power supplies, including an internal
temperature compensated reference source, internal reference, sawtooth generator, pulse width modulator, output stage
and various protection circuits.
