I want to design an efficient LiFePO4 charger and Analog Devices offer the ADP5063 however for a 5V input its efficiency is too low because it is a linear design. The related part - the ADP5065 is an efficient switch-mode design however the datasheet does not explicitly mention LiFePO4 yet e.g. on page 27 of the datasheet it shows that the charge termination voltage is programmable and to e.g. 3.6V which would suit this chemistry. Can the ADP5065 be used with LiFePO4?
Please can you help ...many thanks
