Description

The TL594 is a fixed frequency pulse width modulation control circuit, incorporating the primary building blocks required for the control of a switching power supply. linear sawtooth oscillator is frequency programmable by two external components, RT and CT. CT Functional Table Input/Output Controls Grounded @ Vref Output Function Single ended PWM @ Q1 and Q
