Typical Mobile PC Application
The performance of these new devices has been tested
in circuit and correlates well with performance predic-
tions generated by the system models. An advantage
of this new technology platform is that the MOSFETs
it produces are suitable for both control FET and syn-
chronous FET applications. This has been demon-
strated with the 3.3V and 5V converters. (Fig 3 and
Fig 4). In these applications the same MOSFET IRF7807
was used for both the control FET (Q1) and the syn-
chronous FET (Q2). This provides a highly effective
cost/performance solution.

Figure 2: Q
oss Characteristic
For the synchronous MOSFET Q2, R
ds(on) is an im-
portant characteristic; however, once again the impor-
tance of gate charge must not be overlooked since it
impacts three critical areas. Under light load the
MOSFET must still be turned on and off by the con-
trol IC so the gate drive losses become much more
significant. Secondly, the output charge Q
oss and re-
verse recovery charge Q
rr both generate losses that
are transfered to Q1 and increase the dissipation in
that device. Thirdly, gate charge will impact the
MOSFETs’ susceptibility to Cdv/dt turn on.
The drain of Q2 is connected to the switching node
of the converter and therefore sees transitions be-
tween ground and V
in. As Q1 turns on and off there is
a rate of change of drain voltage dV/dt which is ca-
pacitively coupled to the gate of Q2 and can induce
a voltage spike on the gate that is sufficient to turn
the MOSFET on, resulting in shoot-through current .
The ratio of Q
gd/Qgs1 must be minimized to reduce the
potential for Cdv/dt turn on.
