description
The TL594 incorporates all the functions required in the construction of a pulse-width-modulation control circuit
on a single chip. Designed primarily for power-supply control, these devices offer the systems engineer the
flexibility to tailor the power-supply control circuitry to a specific application.
The TL594 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 with a precision of 1%, an undervoltage lockout
control circuit, and output control circuitry.
The error amplifiers exhibit a common-mode voltage range from –0.3 V to V
CC
–2 V. The DTC comparator has
a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating
RT to the reference output and providing a sawtooth input to CT, or it can be used to drive the common circuitry
in synchronous multiple-rail power supplies.
The uncommitted output transistors provide either common-emitter or 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 possibility of either output being pulsed twice during
push-pull operation. The undervoltage lockout control circuit locks the outputs off until the internal circuitry is
operational.
The TL594C is characterized for operation from 0

C to 70

–40
