Product Summary

The TL494ID is a pulse-width-modulation control circuit. It incorporate on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control circuit. Designed primarily for power supply control, these devices offer the systems engineer the flexibility to tailor the power supply control circuitry to his application.

Parametrics

TL494ID absolute maximum ratings: (1)supply voltage: 41V; (2)amplifier input voltage: VCC+0.3V; (3)collector output voltage: 41V; (4)collector output current: 250mA; (5)operating free-air temperature range: -25 to 85℃; (6)storage temperature range: -65 to 150℃.

Features

TL494ID features: (1)complete PWM power control circuitry; (2)uncommltted 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)circuit architecture allows easy synchroniztion.
