DESCRIPTION
The IP1060 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, sawtooth generator,
pulse width modulator, output stage and various
protection circuits.
