Isolated DC-DC converters deliver outputs down to 1.8V

Ultimate Renaissance has introduced a range of isolated DC-DC converters for distributed power architectures, including low output voltage models for 1.8V supplies. The converters deliver up to 8A output current in an industry-standard 8-pin format, to combine high power delivery and compatibility with existing board layouts.

The new Laritek LT EC 2SC series is a family of small-outline, single output converters measuring 50.8mm x 40.64mm in an open frame format. Efficiency up to 91% allows designers flexibility when configuring power architectures to meet specific system requirements.

Two product streams are available, supporting either 24V or 48V nominal input voltage. Both types deliver output power from 14.4W at 1.8VDC output, up to a maximum of 25W including 5VDC at 5.0A, 12VDC at 2.0A, and 15VDC at 1.6A. Output regulation is ± 0.5% of maximum for each model.

The LT EC 2SC delivers 100% of output power at operating temperatures up to 60°C. Maximum operating ambient temperature is 71 °C, with –2.5%/°C derating above 60 degrees. There is continuous output short circuit protection, output current limiting, output overvoltage protection and thermal shutdown at case temperature 120°C, while the fixed 300 kHz switching frequency allows for easier EMC management.
