Description
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.
