Description

The TL493, TL494. end TL495 each Incorporate on a single monolithic chip all the functions required In the construction of a pulse-widthmodtistion control cWcult Designed prWitarlly for power supply control. has. d.vic.s offer the systems engineer the flex,dity to teilor th. power supply control circuitry to his apphcation.

The TL493 contains sri error amplifier. current- limiting amplifier, an on-chip adjustable oscilator. a dead-time control comperator. pIsesteering control flip-flop, a 5-volt. 5%-precision r.guiutor. and output-control circuits.

The error amplitlet exhibits a common-mode voltage range from -0.3 volts to VCC -2 volts. Tb. current-limit amplifier exhibits a common- mode voltage range from —0.3 volts to 3 volts with an offset voltage of ippioxiniCtely 80 millivolts in series with the inverting input to eisa circuit design requir.m.nts, The d.ed?tirne control comparator has a fixed offset that provides approximately 5% deed time when externally altered. The on-chip oscillator may be bypassed by terminating frj- (pin 81 to the refer.nce output and providing a sawtooth input to C’! (pin 51, or It may be used to drive the common ckcuit. In synchronous multiple-rail power supplies.
