3.6. Push-Pull Converter Example
The Push-Pull converter of Figure 20 uses 2-Wire Ping Pong output mode. As shown in the timing diagram, the
integrator reset occurs when the inputs of both the PH1 and PH2 drivers are low. As shown, TRST is connected to
VDD, selecting the default value of t R (250 ns). Assuming an 80% maximum duty cycle, this value of t R would
deliver specified accuracy over a PWM frequency range of 50 to 400 kHz. Frequencies above 400 kHz would
require the selection of a lower t R value by connecting a resistor from TRST to ground.
