LINEAR INTEGRATED CIRCUIT

PULSE-WIDTH-MODULATION

CONTROL CIRCUIT

SOP-16

DESCRIPTION

The UTC TL594 is a PWM (Pulse Width Modulation) control

circuit, incorporating two error amplifiers, an on-chip adjustable

oscillator, a DTC (Deadtime Control) comparator, a pulse-steering

control flip-flop, a regulator rated 5V with 1% accuracy, an UVLO

(Undervoltage Lockout) control circuit and an output control circuit.

The two error amplifiers have a common-mode voltage varies from

-0.3 V to VCC-2 V. The DTC comparator with a fixed-offset offers

dead time nearly 5%. The UVLO circuit forbids the output until the

internal circuitry is operational. The internal oscillator is used to drive

the common circuits in synchronous multiple-rail power supplies,

when be bypassed by terminating RT to the reference output and

providing an external input of sawtooth to CT.

DIP-16

The uncommitted output transistors have the capabilities of

either common-emitter or emitter-follower output. The output control

can select the push-pull or single-ended output operation for each

device. This chip is not allowed to appear the double pulse status for

either output during push-pull output operation due to its structure.

The UTC TL594 is generally used for the power supply control

circuits, which apply to a large area.

FEATURES

* Adjustable dead time

* Uncommitted outputs transistor rated to 200mA sink or source

current

* Single-Ended or Push-Pull operation selected by output control

* Double pulse is not allowed at either output due to its architecture

* 5V Internal reference voltage (1% accuracy)

* UVLO under the low V_CCstatus
