Application ideas

Equation 35
If C60 is used in the current sensing network the IMON function and the average current
limit feature are not available, since the DC sensed current is almost equal to zero (see
for details).
This application idea has been verified for IMVP7 VCCIO and PCH core supply, 1.05 V rail.
The 1.05 V rail is required to provide up to 16 A, with 8 A load transient in 150 ns. The
following setup has been tested:
●
Output capacitor: 4x330F/6m
Ω + 8x10 F/X5R
●
Inductor: 0.5H/26.9ARMS/0.86m
Ω
●
C15=100 nF; C60=3.3 nF; R31=R32=3.3 k
Ω; C30=100 pF; R8=300 kΩ
The DC and AC performances have been evaluated.
Figure 50.
Load line disabled – VCCIO Supply example
The measured output voltage is almost constant in the full load range, with a maximum drift
lower than 0.2 mV.
The output voltage ripple is close to 17 mV peak-to-peak, from 1 A to 16 A output load.
