Product Summary
The TL494CDR2G is a pulse-width-modulation control circuit. The TL494CDR2G 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. The TL494CDR2G 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
TL494CDR2G absolute maximum ratings: (1)VCC Supply voltage: 41 V; (2)VI Amplifier input voltage VCC: + 0.3 V; (3)VO Collector output voltage: 41 V; (4)IO Collector output current: 250 mA; (5)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260 ℃; (6)Tstg Storage temperature range: –65 to 150 ℃.
Features
TL494CDR2G 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.
