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.
