3 Description
The TPS546D24S is a highly integrated, non-isolated
DC/DC converter that expands on the TPS546D24A
by adding manufacturer-specific PMBus commands
and Extended Write Protect and Passkey. This feature
improves security against malicious access to the
PMBus by restricting Write capability with greater
resolution than the standard Write Protect command.
TPS546D24S is capable of high frequency operation
and 40-A current output from a 7-mm × 5-mm
package. Two, three, and four TPS546D24S devices
can be interconnected to provide up to 160 A on a
single output. The device has an option to overdrive
the internal 5-V LDO with an external 5-V supply
through the VDD5 pin to improve efficiency and
reduce power dissipation of the converter.
The TPS546D24S 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
gives 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
TPS546D24S 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.
