DescriptionThe TL594 device incorporates all the functions
required in the construction of a pulse-width-
modulation (PWM) control circuit ona single chip.
Designed primarily for power-supply control, this
device offers the systems engineer the flexibilityto
tailor the power-supply control circuitrytoa specific
application.
The TL594 device contains two error amplifiers, an
on-chip adjustable oscillator,a dead-time control
(DTC) comparator,a pulse-steering control flip-flop,a
5-V regulator witha precisionof 1%, an undervoltage
lockout control circuit, and output control circuitry.
The uncommitted output transistors provide either
common-emitteror emitter-follower output capability.
Each device provides for push-pull or single-ended
output operation, with selection by means of the
output-control function. The architecture of these
devices prohibits the possibilityof either output being
pulsed twice during push-pull operation. The
undervoltage lockout control circuit locks the outputs
off until the internal circuitryis operational.
