• Manufacturer Part Number: PEF2023
• Description: ISDN DC Converter Circuit IDCC
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

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
detection level. To get low power dissipation the value of resistor R
possibile. The minimum current through R
(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
dissipation the value of resistor R
value of resistor R
current is about 100 A.
