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 ope-
rating temperature range.
State of the art packageing and automated
manufacturing ensures cost-effectiveness and
short lead times.
