ISL6505
Resistors R20, R21
These two act as a resistor divider off the V OUT1 output; the
common connection is brought into the FB1 pin. Use the
following equation to determine them:
V OUT1 = 0.8V * (R20 + R21)/R21.
V OUT1 is expected to be between 1.2V and 1.5V. Note that
the undervoltage detection for this output will be typically
80% of whatever the output voltage is set at.
The sum of (R20 + R21) should equal approximately 1.2 to
1.5k ?, in order to draw about 1mA of current. If the current is
too low (resistors are too high in value), there might be a
small offset error due to the input current of the FB1 pin. On
the other extreme, the current can go as high as 10mA, in
order to meet the minimum load current requirement.

C OUT1 should be chosen as explained in the Linear
Regulator (V OUT1 ) Compensation section.
Application Circuit
Figure 13 shows a typical application circuit for the ISL6505.
The circuit provides the 3.3V DUAL /3.3V SB voltage, the
Ethernet/LAN V OUT1 voltage, the 1.2V VID voltage
identification output, and the 5V DUAL keyboard/mouse
voltage from +3.3V, +5V SB , +5V, and +12VDC ATX supply
outputs. Q4 can also be a PNP transistor, such as an
MMBT2907AL. For additional, more detailed information on
the circuit, including a Bill-of-Materials and circuit board
description, see Application Note AN1053. Also see Intersil
