The TL494 device 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 flexibility to tailor the power-supply control circuitry to a specific application.

The output PWM frequency can be adjusted within the range of 300Hz-100KHz, and the duty cycle can be adjusted up to 96%. The output driving ability is strong, and the signal is stable.
