Other Parts Discussed in Thread: TPS51100, TPS51200, TPS51206

We are design a controller based card with DDR3 discrete chips. To supply Vref and VTT power, we are planning to use TPS51100 device.

Can you please suggest if you have any advanced device for this requirement.

Thanks,

Hi Chandru,

We have TPS51100, TPS51200 and new TPS51206 for VTT application. TPS51206 will be released soon. TPS51206 has similar performance with TPS51200 and TPS51100. But it reduced board area and BOM cost. 1. only 1x10uF VTT output capacitor is required. 2 Implement VDDQ voltage sensing input and no external voltage divider resistors. 3. 2x2mm SON package with 73% reduction of IC footprint vs TPS51100. Please review attached file.

Thanks,

Nancy
