Description

TL494CDR Regulator Positive Output Step-Up, Step-Down, Step-Up/Step-Down DC-DC Controller IC

Description

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 VCC – 2 V. The dead-time control

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 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.
