Overview
The PEB/F 2023 is a pulse width modulator circuit designed for fixed-frequency
switching regulators with very low power consumption.
In telephone and ISDN-systems a high conversion yield is crucial to maintain
functionality in all supply conditions via S- or U-interfaces. The PEB/F 2023 design and
technology realizes high conversion efficiency and low power dissipation. The PEB/F
2023 is fully compatible with the ITU-power recommendations of the S-interface. For
these reasons the PEB/F 2023 is especially suited for telephone and ISDN-
environments.
Coupled with a few external components it can provide a stable 5V DC-supply for
subscriber terminals (TE’s) or network terminators (NT’s). It can additionally be
programmed for higher output voltages, e.g. to supply the S-lines.
It should be recognized that the PEB/F 2023 can also be used in numerous DC/DC-
conversion systems other than ISDN-power supplies. For example, in a special supply
voltage range the PEB/F 2023 can be supplied from a 12V battery.
