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). An internal−linear sawtooth oscillator
is frequency−programmable by two external components,
RT and CT. The approximate oscillator frequency is
determined by:
fosc ^
Output pulse width modulation is accomplished by
comparison of the positive sawtooth waveform across
capacitor CT to either of two control signals. The output is
enabled only during that portion of time when the sawtooth
voltage is greater than the control signals. Therefore, an
increase in control−signal amplitude causes a corresponding
linear decrease of output pulse width. (Refer to the Timing
Diagram shown in Figure 2.)

pin varies from 0.5 V to 3.5 V. Both error amplifiers have a
common mode input range from −0.3 V to (VCC −2.0 V), and
may be used to sense power supply output voltage and
current. The error−amplifier outputs are active high and are
ORed together at the noninverting input of the pulse−width
modulator comparator. With this configuration, the
amplifier that demands minimum output on time, dominates
control of the loop.
The MC34060A has an internal 5.0 V reference capable
of sourcing up to 10 mA of load currents for external bias
circuits. The reference has an internal accuracy of ±5% with
a typical thermal drift of less than 50 mV over an operating
temperature range of 0° to +70°C.

The control signals are external inputs that can be fed into
the dead−time control, the error amplifier inputs, or the
feed−back input. The dead−time control comparator has an
effective 120 mV input offset which limits the minimum
output dead time to approximately the first 4% of the
sawtooth−cycle time. This would result in a maximum duty
cycle of 96%. Additional dead time may be imposed on the
output by setting the dead 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
