Product Details

ISDN Remote Power Controller (IRPC)
**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.
