Figure 10. PCB and Components Layouts
Figure 11. PCB and Components Layouts
Figures 10 and 11 show the demo board layout.
Considering the flexibility in the power mosfet configuration (up to three mosfet for both high side and low side),
it is possible to obtain different application idea with the same board.
In the following paragraphs, it will be described the standard demo-board configuration (8A) and the high current
configuration.
APPLICATION IDEA: 5V TO 12V INPUT; 0.9V TO 5V / 8A OUTPUT
This is a typical bus termination application in which the output voltage is programmed by the switch to 1.2V typ
(it can range from 0.9V to 5V) and the maximum output current is of 8A DC. The power mosfet are configured
with one STS12NF30L (30V, 10m
typ @ Vgs=4.5V ) for both hgih side and low side.
Inductor selection
Since the maximum output current is 8A, to have a 15% ripple (1A) in worst case the inductor chosen is 4.1
μ
H.
SUMIDA CEE125 series inductor has been chosen with a 4.2
μ
A typical value.
