The TPS53831RWZR is a D-CAP+™ mode integrated buck converter for DDR5 on-DIMM power supplies. The converter has a configurable current range to provide VDD, VDDQ, and VPP voltages for DRAM chips on DIMM modules. The high current rail can be configured as 2-phase or 2 outputs to provide up to 12A (or 6A + 6A) and is controlled in D-CAP+™ mode. The converter also features internal compensation for ease of use and reduced external components.
The converter offers a full suite of telemetry functions including input voltage, output voltage and output current. Overvoltage, undervoltage, overcurrent limit, and thermal protection are also provided.
Features
Single device design to support DDR5 applications
3 outputs supporting VDD (1.1V), VDDQ (1.1V), and VPP (1.8V) with an optional 4th output (VDD2)
For 3 outputs, VDD (SWA duplex) is 12A, VDDQ (SWC) is 6A, VPP (SWD) is 5A with 3 outputs
For 4 outputs, VDD1(SWA) is 6A, VDD2(SWB) is 6A, VDDQ(SWC) is 6A, VPP(SWD) is 5A
Differential remote sensing: VDD, VDDQ and VPP
D-CAP+™ control for fast transient response
Wide input voltage: 4.5 V to 15 V
Programmable internal loop compensation
Cycle-by-cycle current limiting per phase
Programmable frequency: 500 kHz to 1.375 MHz
Supports I2C and I3C bus interfaces for voltage, current, power, temperature and fault condition telemetry
Over-current, over-voltage, and over-temperature protection
Persistent register (black box) function
Low quiescent current
