Design challenges

Economical, two-MOSFET design - low QG(tot) & low FOM for best efficiency
Step-down of voltage while stepping up current
D1 and D2 can be exchanged for MOSFETs for higher efficiency

MOSFET and GaN FET Handbook

Drawing on over 20 years’ of experience, the MOSFET and GaN FET Application Handbook: A Power Design Engineer’s Guide brings together a comprehensive set of learning and reference materials relating to the use of MOSFETs and GaN FETs in real world systems.
