The TPSM8D6B24 is a
highly integrated, easy-to-use, non-isolated DC/DC buck
power module. The TPSM8D6B24
provides two 25-A independent
outputs or a single stacked 2-phase 50-A output.
The device has an option to overdrive the internal 5-V
LDO with an external 5-V supply to enable a lower input
voltage range down to 2.95 V and improve the efficiency of
the converter.
The TPSM8D6B24 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 1-MHz 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 TPSM8D6B24
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.
