The TL493, TL494, and TL495 are pulse‑width‑modulation control ICs that integrate error amplifiers, current‑limit amplifiers, on‑chip oscillators, dead‑time control, and output‑control circuits. They support push‑pull or single‑ended operation and provide flexible dead‑time and output‑steering features for power‑supply designs.
The document lists absolute maximum ratings, recommended operating conditions, electrical characteristics such as supply voltage range, oscillator frequency, collector output current, and timing component values. It also includes parameter measurement information, typical characteristic curves, and functional block diagrams for design reference.
| Supply voltage (Vcc) | 7 V to 40 V |
|---|---|
| Oscillator frequency | 1 kHz to 300 kHz |
| Operating temperature range (TL4941) | -25 °C to 85 °C |
They operate from 7 V up to 40 V supply voltage.
The on‑chip oscillator can be set between 1 kHz and 300 kHz.
The TL4941 is specified for operation from –25 °C to 85 °C.
