Figure 10. Output current regulation waveforms
Figure 11 shows the magnitude of the off time tOFF versus COFF and ROFF values. It can be
approximately calculated from the equations:
Equation 1
tRCFALL = 0.6 · ROFF · COFF
tOFF = tRCFALL + tDT = 0.6 · ROFF · COFF + tDT
where ROFF and COFF are the external component values and tDT is the internally generated
deadtime with:
Equation 2
20 K
  ROFF  100 K
0.47 nF
 COFF  100 nF
tDT = 1 µs (typical value)
Therefore:
Equation 3
tOFF(MIN) = 6.6 µs
tOFF(MAX) = 6 ms
