must always be set to 3.3 V (R1 = 5.36 k
). This sets the output voltage of both the V
OBus and VOSeq outputs.
The output voltage of the 3.3-V input (nonisolated) modules, U2 and U3, can be set to any voltage over the
range, 0.8 V to 2.5 V. In this example, they are set to 2.5 V (R2 = 2.32 k
) and 1.8 V (R3 = 6.65 k),
respectively. Figure 27 shows the power-up waveforms from Figure 28 when the Track input to all three modules
are simply connected together.
The converter provides input power to the downstream nonisolated modules via the VOBus output. This output
rises first to allow the nonisolated modules to complete their power-up initialization. The VOSeq (3.3 V), V(POL)1
(2.5 V) and V(POL)2 (1.8 V), outputs supply the load circuit, and rise simultaneously when the converter removes
the internal ground signal to its own Track input. The VOSeq output rises with the outputs from the nonisolated
modules, until it reaches its set-point voltage.
