Description
The ROM Micro Size DC/DC-Converter has been designed for isolating resp. converting DC Power Rails.
It provides a small micro-size package, high efficiency, low output ripple, high 3kVDC Isolation and an
extended –40°C to +85°C operating temperature range.
State of the art packaging and automated manufacturing ensures cost-effectiveness and short lead times.
