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.
