Application Notes
- Minimizing FET Losses For a High Input Rail Buck Converter (Rev. A)PDF, 168 Kb, Revision: A, File published: Apr 23, 2013
Engineers often face the challenge of choosing the input voltage rail that works best for the DC-DCconverter at the point-of-load (POL). High voltage rails, above 12 V, usually demand intermediateregulation stages that reduce overall efficiency and add to cost. However, the new generation of regulatorand controller ICs afford POL regulation from these high input rails directly. Typically the
