DESCRIPTION

a Stable 5-V Reference Supply With Tolerance Circuit Architecture Allows Easy Synchronization The TL494 incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application. The TL494 contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits. The error amplifiers exhibit a common-mode voltage range from 0.3 V to V CC The dead-time control comparator has a fixed offset that provides approximately 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 drive the common circuits in synchronous multiple-rail power supplies. The uncommitted output transistors provide either common-emitter or emitter-follower output capability. The TL494 provides for push-pull or single-ended output operation, which can be selected through the output-control function. The architecture of this device prohibits the possibility of either output being pulsed twice during push-pull operation. The TL494C is characterized for operation from C to The TL494I is characterized for operation from C to AVAILABLE OPTIONS PACKAGED DEVICES (1) SHRINK SMALL THIN SHRINK T A SMALL OUTLINE PLASTIC DIP SMALL OUTLINE OUTLINE SMALL OUTLINE (D) (N) (NS) (DB) (PW) C to C TL494CD TL494CN TL494CNS TL494CDB TL494CPW C to C TL494ID TL494IN (1) The DB, NS, and PW packages are available taped and reeled.
