Texas Instruments TL594CD
- Part Number:
- TL594CD
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3752473-TL594CD
- Description:
- 40V, 0.2A 300KHz PWM controller with UVLO
- ECAD Model:
-
- Datasheet:
- tl594
Description
The TL594 is a pulse-width-modulation (PWM) control circuit designed for power-supply control. It incorporates all the necessary functions for PWM control on a single chip, including two error amplifiers, an adjustable oscillator, a dead-time control comparator, a pulse-steering control flip-flop, a 5-V regulator, an undervoltage lockout control circuit, and output control circuitry.
Features
Complete PWM power-control circuitry
Uncommitted outputs for 200-mA sink or source current
Output control selects single-ended or push-pull operation
Internal circuitry prohibits double pulse at either output
Variable dead time provides control over total range
Internal regulator provides a stable 5-V reference supply trimmed to 1%
Circuit architecture allows easy synchronization
Undervoltage lockout for low-Vcc conditions
Applications
Power-supply control
Synchronous multiple-rail power supplies
Motor control
Lighting control
Battery chargers
