3 Description
The TL494 device incorporates all the functions
required in the construction of a pulse-widthmodulation
(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 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, 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 device provides for push-pull or singleended
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 TL494 device is characterized for operation from
0°C to 70°C. The TL494I device is characterized for
operation from –40°C to 85°C.
TL494CNSRG4屬于集成電路(IC) > PMIC - 穩(wěn)壓器 - DC DC 開關(guān)式控制器。美國(guó)德州儀器公司制造生產(chǎn)的TL494CNSRG4DC-DC 開關(guān)控制器PMIC(電源管理集成電路)DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC,其配置為生成高于(突升或步升)或低于(突降或步降)輸入電源的輸出電源電壓。其他拓?fù)浣Y(jié)構(gòu)可能包括:降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。
