TL494 controller equivalent, smps controller.
* Internal regulator provides a stable 5V reference supply trimmed to 5%
* Uncommitted output TR for 200mA sink or source current
* Output control for push-pu.
The TL494 is used for the control circuit of the PWM switching regulator. The TL494 consists of 5V reference voltage circuit, two error amplifiers, flip flop, an output control circuit, a PWM comparator, a dead time comparator and an oscillator. This.
