SWITCHING CONTROLLER
The TL494 is used for the control circuit of the PWM switching regulator. Where TL494CN can be used? Does TL494CN have alternative parts? What are TL494CN specifications? Today, Magi will tell you the answers.
TL494CN
The TL494 device incorporates all the functions required in the construction of 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 TL494 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits.
