description/ordering information  
The TL594 incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control  
circuit on a single 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 contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC)  
comparator, a pulse-steering control flip-flop, a 5-V regulator with a precision of 1%, an undervoltage lockout  
control circuit, and output control circuitry.  
The error amplifiers have a common-mode voltage range of −0.3 V to V  
− 2 V. The DTC comparator has a  
CC  
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 sawtooth 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 these devices prohibits the possibility of either output being pulsed twice during  
push-pull operation. The undervoltage lockout control circuit locks the outputs off until the internal circuitry is  
operational.  
The TL594C is characterized for operation from 0°C to 70°C. The TL594I is characterized for operation from  
−40°C to 85°C.
