TL494 - Switch mode Pulse Width Modulation Control Circuit

The TL494 is a fixed−frequency pulse width modulation control circuit, incorporating the primary building blocks required for the control of a switching power supply. (See Figure 1.) An internal−linear sawtooth oscillator is frequency− programmable by two external components, RT and CT. The approximate oscillator frequency is determined by:

reflected voltage VR is the volatage across the primary winding when the switch Q1 is turned off. This also affects the maximum VDS rating of Q1.The maximum drain to source voltage is given by: (3) Where: Vspike is the voltage spike caused by the leakage inductance of the transformer. For a starting point assume Vspike is 30% of VDSmax.
