Dead Time
The amount of dead time determines the maximum duty cycle that can be achieved. The Dead Time and the frequency of
operation will determine the duty cycle.
Selecting Rset and Cset
To select values for Rset and Cset perform the following steps to insure the smallest Dead Time..
1) Determine what frequency is required for your design.
2) Use Figure 4 to select a capacitor value for Cset that will provide the highest duty cycle (shortest Dead Time) at
the frequency required.
3) Calculate the value of Rset using the formula:
Note small values of Rset increase power consumption for the PWM5031 and small values of Cset may make PCB and
stray capacitance a source of error.
