Using the TPS51916EVM-746 Complete DDR2, DDR3, DDR3L, and DDR4 Memory Power Solution Synchronous Buck Controller, 2-A LDO, Buffered Reference
Description
The TPS51916EVM-746 is designed to use a regulated 12-V bus to produce a regulated 1.5-VDDQ output at up to a 20-A load current. The TPS51916EVM-746 demonstrates TPS51916 in a typical DDR3 application with D-CAP2™-mode operation. The EVM also provides test points to evaluate the performance of the TPS51916.
Typical Applications
• DDR2/DDR2/DDR3L/DDR4 memory power supplies
• SSTL_18, SSTL_15, SSTL_135, and HSTL termination
Features
The TPS51916EVM-746 features:
• D-CAP2™-mode operation with all-ceramic VDDQ output capacitor
• 20-Adc steady-state VDDQ output current
• Support VDDQ prebias start-up
• SW1 and SW2 provides S3, S5 power control
• Optional external VLDOIN voltage for efficiency and flexible operation
• Convenient test points for probing critical waveforms
