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 ISDNenvironments.
