Description
The MC34060A 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).
linear sawtooth oscillator is frequency
programmable by two external components, RT and CT.

For more information refer to Figure 3.
Output pulse width modulation is accomplished by comparison o
Features
- ead time.
 
- control input to a fixed voltage, ranging between 0 V to 3.3 V. The pulse width modulator comparator provides a means for the error amplifiers to adjust the output pulse width from the maximum percent on.
 
- time, established by the dead time control input, down to zero, as the voltage at the feedback pin.
