Q1
Schottky Selection
Rectifier D2 conducts when the upper MOSFET Q1 is off.
The diode should be a Schottky type for low power losses.
The power dissipation in the Schottky rectifier is
approximated by:
UGATE
PHASE
NOTE:
V G-S ≈ V CC - 5V
P COND = I O x V f x (1 - D)
Where: D is the duty cycle = V O /V IN , and
V f is the schottky forward voltage drop

In addition to power dissipation, package selection and
heatsink requirements are the main design tradeoffs in
choosing the Schottky rectifier. Since the three factors are
interrelated, the selection process is an iterative procedure.
The maximum junction temperature of the rectifier must
remain below the manufacturer’s specified value, typically
125 o C. By using the package thermal resistance specification
and the Schottky power dissipation equation (shown above),
the junction temperature of the rectifier can be estimated. Be
sure to use the available airflow and ambient temperature to
determine the junction temperature rise.
