IRF7807/ATRPbF-1

Control FET

Special attention has been given to the power losses

in the switching elements of the circuit - Q1 and Q2.
Power losses in the high side switch Q1, also called the
Control FET, are impacted by the R

ds(on)

 of the MOSFET,

but these conduction losses are only about one half of
the total losses.

Power losses in the control switch Q1 are given by;

P

loss

 = P

conduction

+ P

switching

+ P

drive

+ P

output

This can be expanded and approximated by;

This simplified loss equation includes the terms Q

gs2

and Q

oss

 which are new to Power MOSFET data sheets.

Q

gs2

 is a sub element of traditional gate-source charge

that is included in all MOSFET data sheets. The impor-
tance of splitting this gate-source charge into two sub
elements, Q

gs1

 and Q

gs2

, can be seen from Fig 1.

Q

gs2

 indicates the charge that must be supplied by

the gate driver between the time that the threshold volt-
age has been reached (t1) and the time the drain cur-
rent rises to I

dmax

 (t2) at which time the drain voltage

begins to change. Minimizing Q

gs2

 is a critical factor in

reducing switching losses in Q1.

Q

oss

 is the charge that must be supplied to the output

capacitance of the MOSFET during every switching
cycle. Figure 2 shows how Q

oss

 is formed by the paral-

lel combination of the voltage dependant (non-linear)
capacitance’s C

ds

 and C

dg

 when multiplied by the power

supply input buss voltage.

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.

 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

/Q

gs1

 must be minimized to reduce the

potential for Cdv/dt turn on.
