4.5V to 15V input, 0.35V to 2.0V output, 35A PMBus power module

Two modules can be configured to work in parallel to provide up to a 70A, 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 400kHz and supports a subset of the commands in the PMBus 1.3 specification. The 15mm × 16mm component footprint is easy to solder onto a printed circuit board and allows a compact, point-of-load design.
