Power Distribution Implementation
•
The LTM4601, LTC DC/DC switching micro module gen5V, +3.3V, 1.1V_DSP, and
1.1V_FPGA (see
Figure 9
)
•
4x LTM4601 work in synchronous mode and are controlled by a 4 phase PLL driver
•
TCI6488 power management supports the core voltage scaling for power consumption
auto-control
•
TCI6488 SerDes 1.1V supply comes from FPGA_CORE_1.1v
•
Both LTM4601and TI switching modules support auto-tracking, which is used for silicon power
sequencing control
•
The LTM4604, 4A, (15 mm x 9 mm x 2.3 mm) DC/DC switching regulator gen1.2V,
+1.5V, +1.8V, and +2.5v from either 5V rail or 3.3V rail.
•
-12V is implemented on-board for PrPMC only with max I <= 350mA
