Description
This series is based on the latest generation of
ST’s proprietary “STripFET™” technology. An
innovative layout enables the device to also
exhibit extremely low gate charge for the most
demanding requirements as high-side switch in
high-frequency DC-DC converters. It’s therefore
ideal for high-density converters in Telecom and
Computer applications.
