Features

* q Switched mode DC/DC-converter q Switched mode DC/DC-converter q CCITT (I.430) ISDN compatible q Integrated 200 V power FET (only PSB 2120-P in P-DIP-22) q Low power dissipation q Supply voltage range 10 V to 60 V q Input undervoltage detection q Programmable overcurrent protection q Soft start q

Applications

* in ISDN-Environments Figure 3 shows an example out of the wide application field of the PSB 2120. In the network termination one PSB 2120 supplies the internal IC’s directly from the U
* interface. A second IRPC, also powered from the U-line, supplies the S
* interface if the main supply
