TPSM8S6B24S is a highly integrated, easy-to-use, non-isolated DC/DC buck power module with added manufacturer-specific PMBus commands. The addition of EXTENDED_WRITE_PROTECT and PASSKEY improves security against malicious access to the PMBus by restricting Write capability with greater resolution than the standard Write Protect command.

TPSM8S6B24S is a 25A power module and can source up to 100A with 4 × stackability. The device has an option to overdrive the internal 5V LDO with an external 5V supply to enable lower input voltage range down to 2.95V and improve the efficiency of the converter.

TPSM8S6B24S 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 to provide 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 TPSM8S6B24S converters, powering a single output rail to share a single address to simplify system software, 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.
