Texas Instruments TPSM8S6C24 Synchronous Buck Power Module

Texas Instruments TPSM8S6C24 Synchronous Buck Power Module is a highly integrated, easy-to-use, non-isolated DC/DC buck power module with added manufacturer-specific PMBus® commands. It also includes the addition of EXTENDED_WRITE_PROTECT and PASSKEY, which improves security against malicious access to the PMBus by restricting Write capability with a greater resolution than the standard Write Protect command.

Texas Instruments TPSM8S6C24 is a 35A power module and can source up to 140A with four × stackability. The device has the 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. TPSM8S6C24 power module uses a proprietary fixed-frequency current-mode control with input feed-forward and selectable internal compensation components for minimal size and stability over a wide range of output capacitances.
