APPLICATION INFORMATION
parallel R-C load
Determining CT(min) for a parallel R-C load is more complex. First, the expression for the output voltage as a
function of time is:

Solving for TSTART when VOUT = VIN yields:

Assuming that the device is operating in the retry mode, where CT is charging from 0.5 V to just below 1.5 V
in time (t), CT is defined as:
C

This yields the following expression for CT(min) for a resistive load with power limiting. By substituting the value
calculated for TSTART in equation (18) for dt, CT(min) is determined.
