TPS53832A Integrated Step-Down Digital Converter for DDR5 On-DIMM Power Supply
1 Features
- Single silicon design to support DDR5 applications
- 3 Outputs to supply VDD (1.1V), VDDQ (1.1V) and VPP (1.8V), with optional 4th
Output (VDD2)
- For 3 outputs, 7 A for
VDD(SWA dual phase), 3.5 A for VDDQ(SWC) and 3.5 A for VPP(SWD) with 3 outputs
- For 4 outputs, 3.5 A for
VDD1(SWA), 3.5 A for VDD2(SWB), 3.5 A
for VDDQ(SWC), and 3.5 A for VPP(SWD)
- Differential remote sense: VDD, VDDQ, and VPP
- D-CAP+™ control for fast transient response
- Wide input voltage: 4.5 V to 15 V
- Programmable internal loop compensation
- Per-phase cycle-by-cycle current limit
- Programmable frequency: 500 kHz to 1.375 MHz
- Support I2C and I3C Bus interface for telemetry of voltage, current,
power, temperature, and fault conditions
- Overcurrent, overvoltage, over-temperature protections
- Persistent register (black box) feature
- Low quiescent current
- 5 mm × 5 mm, 35-Pin, QFN PowerPad™ package
