KA7500
Description
The KA7500 incorporate on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control
circuit. Designed primarily for power supply control ,these devices offer the systems engineer the flexibility to tailor the power
supply control circuitry to hos application. The K A7500 contains an error amplifier , anon-chip adjustable oscillator ,a dead- time
control comparator
,pulse-steering control flip-flop ,a 5-volt, 1% precision regulator , and output-control circuits. The error amplifier
exhibits a common-mode voltage range from -0.3 volts to Vcc -2 volts .The dead time control comparator has a fixed offset that
provides approximately 5% deed time when externally
altered. The on-chip oscillator maybe bypassed byterminating RT (pin 6)
to the reference output and providing a sawtooth input to Ct (pin 5) ,or it may be used to drive the common circuits in
synchronous multiple-rail power supplies . Theuncommitted output transistors provide either common circuits in synchronous
