8.1 Application Information

The schematic of Figure 31 shows a typical application for TPS65295. For VDDQ buck, the PVIN supports 4.5-V to 18-V input range with 1.2-V VDDQ output, the continuous current capability is 8 A. Usually the PVIN_VPP and VCC_5V can share one 5-V power input and supports 2.5-V VPP output with 1-A continuous current capability, of course the PVIN_VPP can be lowered down to a 3.3-V power supply. The VLDOIN power input usually is connected to VDDQ output, while also it can be connected to external 1.2-V power supply input. The VTTREF output voltage will follow the ½ VDDQSNS voltage, and VTT output voltage will follow the VTTREF output voltage, this is required by DDR4 power supply standard.
