temperature by calculating the temperature rise according to
package thermal-resistance specifications. A separate heatsink
may be necessary depending upon MOSFET power, package
type, ambient temperature and air flow.

can be used under special circumstances. The input voltage,
upper gate drive level, and the MOSFET’s absolute gate-to-
source voltage rating determine whether logic-level
MOSFETs are appropriate.
Figure 9 shows the upper gate drive (BOOT pin) supplied by a
bootstrap circuit from V CC . The boot capacitor, C BOOT
develops a floating supply voltage referenced to the PHASE
pin. This supply is refreshed each cycle to a voltage of V CC
less the boot diode drop (V D ) when the lower MOSFET, Q 2
turns on. Logic-level MOSFETs can only be used if the
MOSFET’s absolute gate-to-source voltage rating exceeds
the maximum voltage applied to VCC.

FIGURE 9. UPPER GATE DRIVE - BOOTSTRAP OPTION
Figure 10 shows the upper gate drive supplied by a direct
connection to V CC . This option should only be used in
converter systems where the main input voltage is +5V DC or
less. The peak upper gate-to-source voltage is approximately
V CC less the input supply. For +5V main power and +12V DC
for the bias, the gate-to-source voltage of Q 1 is 7V. A logic-
level MOSFET is a good choice for Q 1 and a logic-level
MOSFET can be used for Q 2 if its absolute gate-to-source
voltage rating exceeds the maximum voltage applied to V CC .
