cases, one or two percent as a result. The diode's rated
reverse breakdown voltage must be greater than the
maximum input voltage.
PWM2 MOSFET and Schottky Selection
The power dissipation in PWM2 converter is similar to
PWM1 except that the power losses of the lower device is in
a Schottky and not a MOSFET. The power losses of PWM2
converter are distributed between the upper MOSFET and
the Schottky. The equations below describe an
approximation of this distribution and assume a linear
voltage-current switching transitions.

Linear Controllers Transistor Selection
The HIP6020 linear controllers are compatible with both
NPN bipolar as well as N-Channel MOSFET transistors. The
main criteria for selection of pass transistors for the linear
regulators is package selection for efficient removal of heat.
The power dissipated in a linear regulator is
Select a package and heatsink that maintains the junction
temperature below the maximum desired temperature with
the maximum expected ambient temperature.
When selecting bipolar NPN transistors for use with the
linear controllers, insure the current gain at the given
operating V

output load current when the base is fed with the minimum
driver output current.
