PWM controller with multi-topology flexibility
The TL594IPWG4 is a fixed-frequency PWM controller from Texas Instruments that supports buck, boost, flyback, forward converter, half-bridge, full-bridge, and push-pull topologies. It operates from a 7V to 40V supply and switches from 1kHz to 300kHz, with a maximum duty cycle of 97%. Two transistor-driver outputs provide positive output configuration, and the controller includes dead-time control and frequency control inputs for adjusting the switching waveform. No synchronous rectifier or clock sync is provided.
The 16-TSSOP package (4.40 mm width) is a surface-mount footprint common in medium-density designs.
No official successor or direct replacement is recorded in the lifecycle data.
