ADP2441 Precharge Startup

Q 

Does ADP2441 support a precharge startup?

 

A 

Yes, ADP2441 supports a precharged condition. If the output voltage is
precharged prior to enabling, the control logic prevents inductor current
reversal by holding the power MOSFETs off until the soft start voltage reaches
the precharged output voltage on Vfb(feedback).
