STLC3075(2005) 数据手册 ( 数据表 ) - STMicroelectronics

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