Product Overview

The TL594CN is a Pulse-Width-Modulation (PWM) Control Circuit designed primarily for power-supply control and this device offers the systems engineer the flexibility to tailor the power-supply control circuitry to a specific application. The DTC comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating RT to the reference output and providing a saw-tooth input to CT or it can be used to drive the common circuitry in synchronous multiple-rail power supplies. The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Each device provides for push-pull or single-ended output operation, with selection by means of the output-control function. The architecture of this device prohibits the possibility of either output being pulsed twice during push-pull operation. The under-voltage lockout control circuit locks the outputs OFF until the internal circuitry is operational.
  • Complete PWM power-control circuitry
  • Uncommitted outputs for 200mA 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 5V reference supply trimmed to 1%
  • Circuit architecture allows easy synchronization
  • Under-voltage lockout for low-VCC conditions
  • Pb-free product
