2DESCRIPTION

The STLC3055N is a SLIC device specifically de-

signed for WLL (Wireless Local Loop) and ISDN-

Terminal Adaptors and VoIP applications. One of

the distinctive characteristic of this device is the

ability to operate with a single supply voltage (from

+5.5V to +12V) and self generate the negative bat-

tery by means of an on chip DC/DC converter con-

troller that drives an external MOS switch.
