I am designing a battery charger for an existing battery pack design of 28 11000mAh NiMH cells. The goal is to design a charger with a constant current output of 3.0A with low DC ripple. The LT3795 and LT3796 Drivers seem to be a good fit for my application. I would like to update their corresponding evaluation boards to meet the 3.0A CC output.
L3795 Demo Board (DC1827A) 110V LED Controller; 8V to 60Vin, 87Vout @ 0.4A, Spread Spectrum Frequency Modulation.
LT3796EFE Demo Board | 100V LED Controller with Current Monitor; 8V to 85VIN, up to 85VOUT @ 0.4A
I would like to update both of these boards to operate in constant current mode outputting 3.0A. Are you able to provide any direction on how best to accommodate these changes?
I am open to all feedback.
Thank you very much
