3 Description

TPSM8S6C24 is a highly integrated, easy-to-use,

non-isolated DC/DC buck power module with added

manufacturer-specific PMBus commands and 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.

TPSM8S6C24 is a 35-A power module and can

source up to 140-A with 4 × stackability. The device

has an option to overdrive the internal 5-V LDO with

an external 5-V supply to enable lower input voltage

range down to 2.95 V and improve the efficiency of

the converter.

TPSM8S6C24 power module uses a proprietary fixedfrequency

current-mode control with input feedforward

and selectable internal compensation components for

minimal size and stability over a wide range of output

capacitances.
