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, Over-Current, and Thermal shutdown parameters. The interface 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 PCB footprint is easy to solder onto a printed circuit board and allows a compact, point-of-load design.
