TPS546D24S Datasheet | Texas Instruments

Features - Integrated extended security feature - Split rail support: 2.95-V to 16-V PVIN; 2.95-V to 18-V AVIN (4-VIN VDD5 for switching) - Integrated 4.5-mΩ/0.9-mΩ MOSFETs - Average current mode control with selectable internal pensation - 2 ×, 3 ×, 4 × stackable with current sharing up to 160 A, supporting a single address per output - Selectable 0.5-V to 5.5-V output through pin strap or 0.25-V to 5.5-V using PMBus VOUT_MAND - Extensive PMBus mand set with telemetry for VOUT, IOUT, and internal die temperature - Differential remote sensing with an internal FB divider for < 1% VOUT error, - 40°C to +150°C TJ - AVS and margining capabilities through PMBus - MSEL pins pin programming PMBus defaults - 12 selectable switching frequencies from 225 k Hz to 1.5 MHz (8 pin strap options) - Frequency sync in, sync out - Supports prebiased output - 7-mm × 5-mm × 1.5-mm, 40-pin QFN - Drop-in patible with TPS546D24A - Create a Custom Design Using the TPS546D24S with WEBENCH® Power Designer 2 Applications - Data center switches, rack servers - Active antenna system, remote radio and baseband unit - Automated test equipment, CT, PET, and MRI - ASIC, So C, FPGA, DSP core, and I/O voltage PGD/RST_B EN/UVLO AVIN PVIN BP1V5 DRTN MSEL1 MSEL2 ADRSEL VSEL AGND VSHARE SYNC BCX_CLK BCX_DAT PMB_DATA PMB_CLK SMB_ALRT VOSNS GOSNS/FLWR BOOT VDD5 PGND VOUT To Loop Followers To PMBus Simplified Application 3 Description The TPS546D24S is a highly integrated, non-isolated DC/DC converter that expands on the TPS546D24A by adding manufacturer-specific PMBus mands 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 mand. 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....
