Product Summary

The TL494CDR 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 TL494CDR offers the flexibility to tailor the power-supply control circuitry to a specific application.

Parametrics

TL494CDR absolute maxing ratings: (1)VCC Supply voltage: max=41V; (2)VI Amplifier input voltage: max=VCC + 0.3V; (3)VO Collector output voltage: 41V; (4)IO Collector output current: 250mA; (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

TL494CDR 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.
