Image of Texas Instruments' TPSM831D31 Dual Output PMBus Module Texas Instruments' TPSM831D31 is a PMBus™-controlled, dual-output, 4-phase power module that combines a high-performance D-CAP+™ controller with four high-efficiency smart power stages and low-loss inductors into a rugged, thermally-enhanced surface-mount package. The user supplies the input and output capacitors and a few passive components to complete the system. The first output is a 3-phase power stage that can deliver up to 120 A of continuous output current. The second output is a single-phase power stage that can deliver up to 40 A of output current.

The PMBus interface provides for converter configuration of each V_OUT, UVLO, soft-start, overcurrent, and thermal shutdown parameter. The interface provides support for telemetry that can report the actual input voltage, output voltage, output current, and device temperature. The device can report input and output power. The TPSM831D31 supports standard PMBus warning and fault functions. The power module supports PMBus communication speeds up to 1 MHz, with 1.8 V or 3.3 V logic levels. The module supports a subset of the commands in the PMBus 1.3 specification.
