The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable of high frequency operation and 40-A current output from a 7-mm × 5-mm package. Two, three, and four TPS546D24A 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 via the VDD5 pin to improve efficiency and reduce power dissipation of the converter.
The TPS546D24A 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 TPS546D24A 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.
