DC/DC Boost

Often when a system is powered by a battery supply, then often the output voltage needs to boosted to supply a range of actuators, motors, etc. The DC/DC boost circuit offers an output voltage higher than its input.

Design challenges

  • Point of load non-isolated DC/DC boost converter circuit
  • Economical, two-MOSFET design - low QG(tot) and low FOM for best efficiency
  • Easily switch from asynchronous to synchronous conversion depending on choice of high-side diode or MOSFET
  • Lower switch losses improve thermal behaviour
  • LFPAK and CFP (both clip-bond package) allow a high-efficiency DCDC converter solutions, while reducing costs (less heating to dissipate)
  • Possibility to go to higher switching frequency (FSW), which leads to smaller inductances and smaller capacitors
  • Best thermal performance thanks to clip-bonding package

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.
