SMPS Controller
Features Internal regulator provides a stable 5V reference supply
trimmed to 5% Uncommitted output TR for 200mA sink or source
current Output control for push-pull or single-ended operation Variable duty cycle by dead time control (pin 4) Complete
PWM control circuit On-chip oscillator with master or slave operation Internal circuit prohibits double pulse at either output
DescriptionThe 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 con-
trol circuit, a PWM comparator, a dead time comparator and
an oscillator. This device can be operated in the switching
frequency of 1 KHz to 300 KHz.
