DESCRIPTION:
point of load converter
2. CB Certificate from an internationally recognized test house in
accordance with EN 60950.
The VPOL20A-12W-SIP series converters do not have an internal fuse.
However, to achieve maximum safety and system protection, always
use an input line fuse. The safety agencies require a time-delay fuse
with a maximum rating of 25A.
7.1 Layout Design Challenges.
In optimizing thermal design the PCB Prototyping is utilized as a heat sink. Also
some heat is transferred from the VPOL20A-12W-SIP module to the
main board through connecting pins. The system designer or the end
user must ensure that other components and metal in the vicinity of the
VPOL20A-12W-SIP series meet the spacing requirements to which the
system is approved.
Low resistance and low inductance PCB layout traces are the norm and
should be used where possible. Due consideration must also be given to
proper low impedance tracks between power module, input and output
grounds. The recommended VPOL20A-12W-SIP footprint as shown as
figure 8.
