AN-1820LM5032 Interleaved Boost Converter
www.ti.comIn a boost converter, the output capacitor must be chosen to withstand relatively high ripple current compared to an equivalent power buck regulator. The high ripple current flows through the equivalent series resistance (ESR) of the capacitor. ESR increases the capacitor temperature and increases ripple voltage.

NCP81075 - Dual MOSFET Gate Driver, High Performance
www.onsemi.comMOSFETs in a synchronous buck converter. The NCP81075 uses an on−chip bootstrap diode to eliminate the external discrete diode. A high floating top driver design can accommodate HB voltage as high as 180 V. The low−side and high−side are independently controlled and match to 4 ns between the turn−on and turn−off of each other.
