When the input voltage is LOW and current is flowing in the inductor, the upper
MOSFET must be off and the lower MOSFET must be on. Current flows from the
power ground (V
SSO
), through the lower MOSFET and the inductor (L
out
), to the
output.
Finally, when switching between states, both MOSFETs must not be on at the same
time.
7.2 MOSFET driver function
The input, output and gate drive waveforms are shown in
Figure 4
. When the input
voltage goes HIGH, the gate drive to the lower MOSFET immediately goes LOW. This
causes the output current to flow through the source-drain diode of the lower
MOSFET. This causes output voltage to fall from zero to approximately
0.7 V.
After a delay, if the input voltage is still HIGH, the gate drive to the upper MOSFET
goes HIGH. This causes the output voltage to rise to the output stage supply voltage,
V
DDO.
When the input voltage goes LOW, the gate drive to the upper MOSFET immediately
goes LOW. The output voltage falls from V
DDO
, until it is clamped by the source-drain
diode of the synchronous FET at approximately
0.7 V.
After a delay, if the input voltage is still LOW, the gate drive to the lower MOSFET
goes HIGH. The lower MOSFET turns on, and the output voltage rises from
0.7 V to
zero.
7.3 Bootstrap diode
A bootstrap diode is integrated into the design of the PIP201-12M between V
DDC
and
CB.
