Hi team,

Do we have any solution to compete with LTC3351? Customer cares two main specs of this device,

  1. Step-Down CC/CV Charging of One to Four Series Supercapacitors, Vin=12V, 4 capacitors, need to charge to 12V.
  2. Step-Up Mode in Backup Provides Greater, when the main power line is off, need capacitor tp boost to 12V to power the load.

    Hi There:
        

         You can try BQ24780S for this application.

          The BQ24780S is a 1-4 cell battery charge controller with power selection for space-constrained, multi-chemistry portable applications such as notebook and detachable ultrabook. It supports wide input range of input sources from 4.5 V to 24 V, and 1-4 cell battery for a versatile solution.

         The BQ24780S device supports hybrid power boost mode (previously called "turbo boost mode"). It allows battery discharge energy to system when system power demand is temporarily higher than adapter maximum power level. Therefore, adapter does not crash.
