Figure 5
shows the PEB/F 2023 in a non-isolated minimum configuration by using
supply voltage range 1 (for this input voltages also supply voltage range 2 is possible).
The voltage drop over R
6
is the difference between input voltage and undervoltage
detection level. To get low power dissipation the value of resistor R
6
should be as high as
possibile. The minimum current through R
6
is about 100nA, the maximum current is 1mA
(see absolute maximum ratings).

Figure 6
shows the PEB/F 2023 in a non-isolated flyback configuration with transformer
using supply voltage range 0. The voltage drop over R
6
is V
EXT
-1V. To get low power
dissipation the value of resistor R
6
, should be as high as possibile. For calculating the
value of resistor R
6
the minimum current through R
6
is about 100nA and the maximum
current is about 100
