V B5

The PSB 2120 is a Pulse Width Modulator (PWM) circuit designed for fixed-frequency switching

regulators especially for telephony and ISDN-environments.

The PSB 2120 is fully compatible with the CCITT-power recommendations on the “S”-interface.

Coupled with a few external components it can provide a stable 5 V DC-supply for subscriber

terminals (TE’s) or network terminators (NT’s). It can also be programmed for higher output

voltages, e.g. to supply the S-lines with 40 V.

In telephony and ISDN-systems a high conversion yield is crucial to maintain functionality in all

supply conditions via “S”- or “U”-interfaces. The PSB 2120 design and technology realizes high

conversion efficiency and low power dissipation.

It should be recognized that the PSB 2120 can also be used in numerous DC/DC-conversion

systems other than ISDN-power supplies.
