DESCRIPTION
The STLC3065 is a SLIC device specifically de-
signed for WLL (Wireless Local Loop) application.
One of the distinctive characteristics of this de-
vice is the ability to operate with a single supply
voltage (from +5.5V to +15.8V) and self generate
the negative battery by means of an on chip
DC/DC converter controller that drives an external
