TL594
- 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
- Undervoltage lockout (UVLO) for low-VCC conditions
The TL594 device incorporates all the functions required in the construction of a pulse width modulation (PWM) control circuit on a chip. Designed primarily for power-supply control, this device offers the systems engineer the flexibility to tailor the power-supply control circuitry to a specific application.
The TL594 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5V regulator with a precision of 1%, an undervoltage lockout control circuit, and output control circuitry.
The uncommitted output transistors provide either common-source or source-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 these devices prohibits the possibility of either output pulsing twice during push-pull operation. The undervoltage lockout control circuit locks the outputs off until the internal circuitry is operational.
