Typical Applications
DC/DC Converter
The most common AAT4900 applications include a
DC/DC converter output power stage and a MOS-
FET gate drive buffer.
Figure 1 shows a common configuration when used
as a DC/DC converter power stage with synchro-
nous rectification. The enable pin can be used to
force the LX output to a high impedance state under
light load conditions. This enables the output induc-
tor to operate in discontinuous conduction mode
(DCM), improving efficiency under light load condi-
tions. The body diode associated with the low side
switching device gives the AAT4900 inductive
switching capability, clamping the LX node at a
diode drop below GND during the break-before-
make time.
