TL494N Datasheet Pulse-width-modulation Controller

Manufacturer: HTC KOREA

Overview: Pulse-Width-Modulation Control Circuits TL494.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TL494 incorporate on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control, these devices offer the systems engineer the flexibility to tailor ORDERING INFORMATION Device Package the power supply control circuitry to his application.

The TL494 contains an error amplifier, an on-chip adjustable oscillator, a dead-time control parator, pulse-steering control TL494D TL494GD (Halogen Free) TL494N SOP16 16 DIP flip-flop, a 5-volt, 5% precision regulator, and output-control circuit.

The error amplifier exhibits a mon-mode voltage range from -0.3 volts to Vcc -2 volts.
