GS2TX-9A - STMicroelectronics

GS2TX-9A 2 W LAN DC-DC CONVERTER

The GS2TX-9A is a 2.25W unregulated DC-DC converter designed to provide power, voltage regulation and isolation for Local Area Network (CHEAPERNET and ETHERNET) transceivers from a wide range of input voltage, according to IEEE 802.3 Standard. An internal network is added to guarantee soft start at switch-on. ELECTRICAL CHARACTERISTICS (Tamb.= 25° C unless .
