Hi guys, Im looking for a driver IC for a buck Converter topology. I want to reduce 20-21V to 7.4V in order to charge a 2S battery 910mAh. Can you recommend me a good driver IC to use with Arduino? The frequency of the Arduino's PWM will be 31.5 Khz. Thanks in advance!

Commercial chargers are a dime a dozen and have been engineered to be safely operated to prevent fires etc.

Edit

Look into the LT3650.
