Schottky Selection
Rectifier D
2
is a clamp that catches the negative inductor swing
during the dead time between turning off the lower MOSFET
and turning on the upper MOSFET. The diode must be a
Schottky type to prevent the lossy parasitic MOSFET body
diode from conducting. It is acceptable to omit the diode and let
the body diode of the lower MOSFET clamp the negative
inductor swing, but efficiency will drop one or two percent as a
result. The diode’s rated reverse breakdown voltage must be
greater than the maximum input voltage.
HIP6004E DC-DC Converter Application
Circuit
Figure 11 shows an application circuit of a DC-DC Converter
for a microprocessor. Detailed information on the circuit,
including a complete bill-of-materials and circuit board
description, can be found in AN9916. This application note
also contains the application information for ISL6525, an
controller IC designed to meet the VTT voltage and power-
up sequencing specification given in the Intel VRM8.5.
