Product Summary

The TL494CDR is a pulse-width-modulation control circuit.

Parametrics

TL494CDR absolute maximum ratings: (1)VCC, Supply voltage: 41V; (2)VI, amplifier input voltage: VCC+0.3V; (3)VO, collector output voltage: 41V; (4)IO, collector output current: 250mA; (5)Tstg, storage temperature range: 150℃.

Features

TL494CDR features: (1)Complete PWM power-control circuitry; (2)Uncommitted outputs for 200mA 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 5V reference supply with 5% tolerance; (7)Circuit architecture allows easy synchronization.
