I'm designing power part, TPS51916 is best part for me.
Could I get reference design of TPS51916 for DDR3 with VIN=5V as following conditions?
(1) D-CAP2, 670KHz, Tracking Discharge mode
(2) VIN (drain of HSFET) = 5V typical
(3) VDDQ = 1.5V, 10A
It should be appreciated if you inform BOM.
Thank you in advance,
Matteo
Hi Matteo,
Thanks for your choosing TPS51916. But E2E forum is not a good place to request reference. Next time please contact your local FAE for help. I attach the following information for your reference based on your application.
1. Schematic as attached:
a. Set D-CAP2, 670kHz, tracking discharge mode, current limit is around 14.5A typ.
b. Output capacitor: 2x100uF ceramic capacitor
c. Output inductor: suggest 0.42uH, P/N: ETQP4LR42AFM from Panasonic. The datasheet is attached too.
d. MOSFET: Recommend CSD86330Q3D from TI.
e. Input capacitor: 2x22uF ceramic capacitor
f. R7 is sunbber resistor and suggest 0805 package
g. Other resistor or capacitor should be 0603 or 0805 or 0402 depends on your PCB layout.
2. Component selection spreadsheet is attached for your reference.
If you have further question, please contact your local FAE directly. You can review the TPS51916EVM user's guide for PCB layout.
Thanks,
Nancy
