5V to 3.3V Buck Converter With 5V Output
This circuit minimizes both board space and cost by eliminating a
second regulator.
VERSA-PAC’s gap serves to prevent core
saturation during the switch on-time and also stores energy for the
+5V load which is delivered during the flyback interval. The +3.3V
buck winding is configured by placing two windings in series while
the +5V is generated by an additional flyback winding stacked on
the 3.3V output. Extra windings are paralleled with primary
windings to handle more current. The turns ratio of 2:1 adds 1.67V
to the +3.3V during the flyback interval to achieve +5V.

3.3V Buck Converter
This circuit utilizes the gap of the VP5-0083 to handle the 12.5
Amp output current without saturating. In each of the five
VERSA-
PAC sizes, the gap is varied to achieve a selection of specific
inductance and current values (see
VERSA-PAC Data Table).
All six windings are connected in parallel to minimize AC/DC
copper losses and to maximize heat dissipation. With
VERSA-
PAC, this circuit works well at or above 300 KHz. Also, the closed
flux-path EFD geometry enables much lower radiation
characteristics than open-path bobbin core style components.
LITHIUM-ION BATTERY TO 3.3V SEPIC CONVERTER
The voltage of a Lithium-Ion Battery varies above and below
+3.3V depending on the degree of charge. The SEPIC
configuration takes advantage of
VERSA-PAC’s multiple tightly
coupled windings. This results in lower ripple current which lowers
noise and core losses substantially. The circuit does not require a
snubber to control the voltage “spike” associated with switch turn-
off, and is quite efficient due to lower RMS current in the windings.
