ispPAC-POWR6AT6 Data Sheet
Figure 3-8 shows the resistor network between the TrimCell #N in the ispPAC-POWR6AT6 and the DC-DC con-
verter. The values of these resistors depend on the type of DC-DC converter used and its operating voltage range.
The method to calculate the values of the resistors R1, R2, and R3 are described in a separate application note.
Voltage Pro?le Control
The Margin / Trim Block of ispPAC-POWR6AT6 consists of six TrimCells. Because all six TrimCells in the Margin /
Trim Block are controlled by a common voltage pro?le control signals, they all operate at the same voltage pro?le.
The voltage pro?le control input comes from a pair of device pins: VPS0, VPS1.
TrimCell Architecture
The TrimCell block diagram is shown in Figure 3-9. The 8-bit DAC at the output provides the trimming voltage
required to set the output voltage of a programmable supply. Each TrimCell can be operated in any one of the four
voltage pro?les. In each voltage pro?le the output trimming voltage can be set to a preset value. There are six 8-bit
registers in each TrimCell that, depending on the operational mode, set the DAC value. Of these, four DAC values
(DAC Register 0 to DAC Register 3) are stored in the E 2 CMOS memory while the remaining register contents are
stored in volatile registers. Two multiplexers (Mode Mux and Pro?le Mux) control the routing of the code to the DAC.
The Pro?le Mux can be controlled by common TrimCell voltage pro?le control signals.

CONTROL
Figure 3-7 shows four power supply voltages next to each DC-DC converter. When the Pro?le MUX is set to Volt-
age Pro?le 3, the DC supply controlled by Trim 1 will be at 0.95V, the DC supply controlled by Trim 2 will be at
1.14V, 1.42V for Trim 3 and 3.13V for Trim 8. When Voltage Pro?le 0 is selected, Trim 1 will set the supply to 1V,
Trim 2 and Trim 3 will be set by the values that have been loaded using I 2 C at 1.2 and 1.5V, and Trim 6 will be set to
3.3V.
The following table summarizes the voltage pro?le selection and the corresponding DAC output trimming voltage.
The voltage pro?le selection is common to all six TrimCells.
