mc34060a, mc33060a http://onsemi.com 6 applications information 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 pin varies from 0.5 v to 3.5 v. both error amplifiers have a common mode input range from ? 0.3 v to (v cc ? 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. figure 3. oscillator frequency versus timing resistance figure 4. open loop voltage gain and phase versus frequency figure 5. percent deadtime versus oscillator frequency figure 6. percent duty cycle versus dead ? time control voltage f, frequency (hz) , open loop voltage gain (db) vol a vol 1.0 10 100 1.0 k 10 k 100 k 1.0 m , excess phase (degrees) a vcc = 15 v vo = 3.0 v rl = 2.0 k dead?time control voltage (v) percent duty cycle (%) 0 1.0 2.0 3.0 3.5 v cc = 15 v c t = 0.001 r t = 47 k v cc = 15 v r t , timing resistance ( ) , oscillator frequency (hz) osc 1.0 k 2.0 k 5.0 k 10 k 20 k 50 k 100 k 200 k 500 k 1.0 m f 1.0 f 0.001 f c t = 0.01 f f osc , oscillator frequency (hz) % dt, percent dead-time, q1 output 500 10 k 100 k 500 k c t = 0.001 f 0.01 f 1.0 k 100 90 80 70 60 50 40 30 20 10 0 100 80 60 40 20 0 500 k 100 k 10 k 1.0 k 500 20 18 16 14 12 10 8.0 6.0 4.0 2.0 0 110 120 ?20 ?40 ?60 ?80 ?100 ?120 ?140 ?160 ?180 0
