3 TPS65086x Variants

In total, there are four variants of the TPS65086x PMIC for the Zynq UltraScale+, as shown in Table 3-1.

Table 3-1 TPS65086x Variant Voltage Comparison

	Programmability	Buck 1	Buck 2¹	Buck 3¹	Buck 4	Buck 5	Buck 6¹	LDOA1	LDOA2	LDOA3
TPS6508640	Pre-programmed	3.3 V	0.85, 0.9 V	1.2 V	0.9 V	1.8 V	1.2, 1.35 V	2.5 V	1.5 V	1.2 V
TPS65086401	Pre-programmed	1.8 V	0.85 V	0.85 V	3.3 V	3.3 V	1.1, 1.2, 1.5 V	1.8 V	1.2 V	1.2 V
TPS6508641	Pre-programmed	External Feedback	0.85 V	1.1, 1.2 V	3.3 V	1.2 V	1.8V	1.8 V	1.2V	1.2V
TPS650861	User programmable	0.41 - 3.575 V						1.35-3.3 V	0.7 - 1.5 V

Multiple voltages may be available through pin strapping; if so, they are separated with a comma.

The first three variants in the table are pre-programmed, varying in their set voltages and sequencing to match the different Xilinx ZU+ MPSoC specifications. The different MPSoCs each variant supports are outlined in the next section. The fourth, the TPS650861 (also denoted TPS65086100), is the user-programmable DIY version, and will be discussed in greater detail in Section 5. All four variants share the same current capabilities, which are shown in Table 3-2.
