No IR2110 is needed, nor any gate driver. Use a PWM control IC with an output that drives low side n-channel FETs. A complimentary emitter follower can buffer the gate drive and provide the peak amperes to drive the FET gate. Otherwise a complimentary FET driver can provide the drive. The topology for this application would be a boost converter as long as isolation is not needed. If galvanic isolation is needed, then a flyback or forward converter is recommended.
