The transition time for buck/boost of TPIC74100-Q1

Other Parts Discussed in Thread: TPIC74100-Q1

I would like to confirm the transition time from buck to boost and from boost to buck for TPIC74100-Q1.

How much is the time?

What is the cause TPIC74100-Q1 has the transition time?

The customer checked it and they feel it is long.

Best regards,

Atsushi Yamauchi

    Hello Yamauchi-san,

    If you look at Figure 14 and Figure 15 (CH1 and CH3 are SW nodes and CH2 is AC coupled Vout), you can make out that switch over from Buck/Boost  or Boost/Buck is really smooth and probably happens within less than 20us.

    Are they facing some issues or it is their observation?

    Regards,
