The TPSM8D6C24 is a highly integrated, easy-to-use, non-isolated DC/DC buck power module. The TPSM8D6C24 provides two 35A independent outputs or a single stacked 2-phase 70A output. Two modules can be stacked for a 4-phase 140A output. The device has an option to overdrive the internal 5V LDO with an external 5V supply to enable a lower input voltage range down to 2.95V and improve the efficiency of the converter.
The TPSM8D6C24 power module uses a proprietary fixed-frequency current-mode control with input feedforward and selectable internal compensation components for minimal size and stability over a wide range of output capacitances.
The PMBus interface with 1MHz clock support provides a convenient, standardized digital interface for converter configuration as well as monitoring of key parameters including output voltage, output current, and internal die temperature. Response to fault conditions can be set to restart, latch off, or ignore, depending on system requirements. Back-channel communication between stacked devices enables all TPSM8D6C24 converters, powering a single output rail to share a single address to simplify system software or firmware design. Key parameters including output voltage, switching frequency, soft-start time, and overcurrent fault limits can also be configured through BOM selection without PMBus communication to support program free power up.
