E-STLC3075 Datasheet - STMicroelectronics

Description
The STLC3075 is a SLIC device specifically designed for WLL (Wireless Local Loop), and ISDN terminal adaptors and VoIP applications. One distinctive characteristic of this device is its ability to operate with a single supply voltage (from +4.5 V to +12 V) and to self generate the negative battery by means of an on-chip DC/DC converter controller that drives an external MOS switch.
