The ROM Micro Size DC/DC converter has been designed for isolating or converting DC power rails where board height
is at a premium. Although it has a micro-size 7.7mm package, it does not compromise on features and offers a high
3kVDC Isolation , a –40°C to +85°C operating temperature range and optional continuous short circuit protection.
