Two transistor-driver outputs with a 97 % maximum duty cycle give it the headroom for low-dropout pre-regulators or high step-down ratios. The switching frequency spans 1 kHz to 300 kHz. The 7 V to 40 V supply range lets it run off a single industrial bus without a separate bias rail. Dead-time control and frequency control are on-chip, so you set the oscillator timing with one resistor and one capacitor, then adjust the dead time with a second resistor — no external clock generator needed.","metaTitle":"TL594CDG4 PWM Controller, 1 kHz–300 kHz, 7 V–40 V, 16-SOIC","metaDescription":"TL594CDG4 PWM controller from Texas Instruments.
