MMPF0100 rise time of regulators for start-up.

[satoshishimoda]

Hi community,

Our customer have a question about MMPF0100.

Please see Figure 6 and Table 11 of MMPF0100 datasheet (Rev.15), tr3 is difined as 0.2ms.

Our customer want to know whether the rise time by SWxDVSSPEED setting.

I feel SWxDVSSPEED changes the slew rate for DVS only, and no effect for rise time when start-up, so the rise time (0.2ms) cannot be changed.

Is my understanding correct?

Or SWxDVSSPEED changes the start-up rise time?

Best Regards,

Satoshi Shimoda

You are right in that the SWxDVSSPEED settings only affect the DVS operation and do not affect the power-on voltage rise time that is fixed and its typical value is 0.2ms.

Have a great day,
Artur
