An internal current source charges a soft-start capacitor which is connected from the sequencing pin to GND. The following equation is used to calculate the soft-start capacitor: Css = soft-start capacitor t ss = required soft-start time n = number of RPMHs Css [nF]= (8.1 x n) x tss[ms] Note: Note9: Operation below 20% load will not harm the converter, but specifications may not be met Vin SEQ GND1 GND3 GND2 NC Trim PGood Sense Vout Vin Vout Vin Vout CTRL Vin Vout(1) Vout(n) Vout(n+1) RPMH(1) RPMH(n) RPMH(n+1) CTRL SEQ GND1 GND3 GND2 NC Trim PGood Sense CTRL Vin SEQ GND1 GND3 GND2 NC Trim PGood Sense CTRL Vin C1 C2 COUT1 COUT(n) COUT(n+1) C3 C4 C5 C6 To sequence multiple power module start-up times, the power good (PGood) pin and the CTRL pin may be used.

After RPMH(n) reaches its set output voltage, it enables RPMH(n+1).
