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.
