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.
