DESCRIPTION
The IP5561 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 zener reference, sawtooth
generator, pulse width modulator, output stage and
cycle by cycle current limit.
