DESCRIPTION
The GS2T12-9S is a 2.25W unregulated DC-DC
converter designed to provide power, voltage regu-
lation and isolation for Local Area Network
(CHEAPERNET and ETHERNET) transceivers
from a wide range of input voltage, according to
IEEE 802.3 Standard.
Enable function, active high, is available with
CMOS/TTL logic operation compatibility.
