Title: Sizing of capacitor, switches - Low Power Integrated Series Parallel Charge Pump
Post by ICD_life on Nov 12^th, 2014, 1:33am

Hello All,

I am designing Series Parallel Charge Pump that is used in Power Management circuit to charge the battery.
Details:
It has variable input < 1V
Output voltage must be > 2V
[no load current limitation defined yet, max 500uA]

Can anybody explain me how to size capacitors and switches for the same? I am using multiple conversion ratio topology so using Series-Parallel capacitor.

Kindly help me understand.

Regards,
