It is possible to configure the ADM8839 to supply up to 400
μ
A
on the
±
15 V outputs by changing its configuration slightly, as
shown in Figure 4.

Figure 4. Current Boost Configuration
The configuration in Figure 4 can supply up to 400
μ
A of current
on both the +15 V and the –15 V outputs. If the load on the
±
15 V does not draw any current, the voltage on the
±
15 V out-
puts can rise up to
±
16.5 V (see Figure 5). In this configuration,
VOUT (Pin 2) is connected to +5VIN (Pin 5).
