Product Summary

The TL494C is a pulse-width-modulation control circuit. It 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, the TL494C offers the flexibility to tailor the power-supply control circuitry to a specific application. The TL494C 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.

Parametrics

TL494C absolute maximum ratings: (1)VCC Supply voltage: max=41 V; (2)VI Amplifier input voltage: max=VCC + 0.3 V; (3)VO Collector output voltage: max=41 V; (4)IO Collector output current: max=250 mA; (5)θJA Package thermal impedance D package: 73 ℃/W; DB package: 82 ℃/W; N package: 67 ℃/W; NS package: 64 ℃/W, PW package: 108 ℃/W; (6)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260 ℃; (7)Tstg Storage temperature range: min=-65 ℃, max=150 ℃.

Features

TL494C features: (1)Complete PWM Power-Control Circuitry; (2)Uncommitted Outputs for 200-mA Sink or Source Current; (3)Output Control Selects Single-Ended or Push-Pull Operation; (4)Internal Circuitry Prohibits Double Pulse at Either Output; (5)Variable Dead Time Provides Control Over Total Range; (6)Internal Regulator Provides a Stable 5-V Reference Supply With 5% Tolerance; (7)Circuit Architecture Allows Easy Synchronization.
