Description
IDTP9167 is a power management device used in conjunction
with the IDTP9165 PMIC to either increase the output current
capability of existing Buck regulator rails, or implement extra
output rails when connected to the PMIC’s controller interface.
The device works as a controlled current source that supplies
current to the load above what the host PMIC can deliver on its
own. Up to four IDTP9167s may be used in parallel to provide an
additional 22A of peak load current capability.
A high-speed 2-wire digital bus connects the IDTP9165 to the
IDTP9167 DPUs to provide control and exchange status
information. The device seamlessly integrates into the PMIC ecosystem and is transparent from a user point of view.
The IDTP9167 comes in a 4mm x 3mm, 12-ld DFN package. It is
guaranteed to operate over the industrial temperature range of
-40°C to +85°C.
