DESCRIPTION  
The TL494 incorporate on a single monolithic chip all the functions  
required in the construction of a pulse-width-modulation control,  
these devices offer the systems engineer the flexibility to tailor  
the power supply control circuitry to his application.  
ORDERING INFORMATION

TL494N  
Package  
16 SOP  
18 DIP  
The TL494 contains an error amplifier, an on-chip adjustable  
oscillator, a dead-time control comparator, pulse-steering control  
flip-flop, a 5-volt, 5% precision regulator, and output-control circuit.  
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% dead time when externally altered. The on-chip  
oscillator may be bypassed by terminating RT (pin 6) to the reference output and providing a sawtooth in put to  
CT (pin 5), or it may be used to drive the common circuits in synchronous multiple-rail power supplies. The  
uncommited output transistors provide either common-emitter or emitter-follower output capability. Each Device  
provides for push-pull or single-ended output operation, which may be selected through the output-control funct  
-ion. The architecture of these devices prohibits the possibility of either output being pulsed twice during push  
-pull operation.
