3 Description
The TPSM846C23 is a 35-A fixed-frequency, PMBus-
compliant, step-down power module, with PMBus
commands that allow for the configuration, control,
and monitoring of key power regulator functions. The
module incorporates the controller, power MOSFETs,
inductor, and associated components into a rugged,
thermally enhanced, surface-mount package. The
user supplies the input and output capacitors along
with a few other passive components to set the
operating parameters of the module. Two modules
can be configured to work in parallel to provide up to
a 70-A, two-phase power solution.
The PMBus interface provides for converter
configuration of output voltage, UVLO, soft start, soft
stop, overcurrent, and thermal shutdown parameters.
The interface also provides support for telemetry that
can report the actual output voltage, output current,
and device temperature. Standard PMBus warning
and fault functions are also supported. The device
supports PMBus communication speeds up to
400 kHz and supports a subset of the commands in
the PMBus 1.3 specification.
The 15-mm × 16-mm component footprint is easy to
solder onto a printed circuit board and allows a
compact, point-of-load design.
