8 Ampere Design Adaptation
Many motherboards do not require the full
12.4 ampere current output. In this case the
IRP6VRM1 can be adapted to lower current
levels by using the assembly options shown.
These options will reduce cost by removing
components and by using smaller die size

MOSFETs. Substitution of a MOSFET for a
FETKY will reduce efficiency somewhat, but
junction temperatures will still remain well
within a safe limit.

Efficiency
Efficiency is required to be at least 80%
at full load. Thanks to the very efficient
IRL3103S and the FETKY IRL3103D1S,
IRP6VRM1 exceeds the required
specification by a wide margin.
Maximum Junction Temperature
Analysis of Q1 junction temperature shows
that it remains within specifications at an
ambient temperature of 50°C, even in still air.
