PDF-Application Report SNVAB May Revised April AN Selecting Inductors for Buck Converters

ABSTRACT This application report provides design information to help select an offtheshelf inductor for any continuousmode buck converter application Contents Introduc. ABSTRACT In many applications one or more lowcost simple to use isolated power supplies working from input voltages up to 100V are needed Traditional solutions use flyback co These operating ranges may be broad and in some cases may overlap It is usually not possible to derive any arbitrary output voltage from the entire range of permissible input voltages There are several factors that can cause this including the inter V-JSAT2-May-15SUN3-May-15MON4-May-15V-BTUE5-May-15V-L/BV-JWED6-May-15THU7-May-15FRI8-May-15V-L/BV-JSAT9-May-15SUN10-May-15MON11-May-15V-BTUE12-May-15V-L/BV-J13-May-15THU14-May-15FRI15-May-15V-L/BV-JSA Recommended for: .
