The UEI series isolated DC/DC converter family offers efficient regulated DC power for printed circuit board mounting, featuring a full 15 Watt or greater output in one square inch of board area.
The UEI15 series provides isolated DC/DC converters in a compact 0.9" x 1.1" x 0.335" open‑frame package. They deliver up to 15 W (or higher) with synchronous‑rectifier topology, stable no‑load operation, and a temperature range of –40 °C to 85 °C. Fixed output voltages from 3.3 VDC to 15 VDC are available, with optional trimming of ±10 %.
The converters include multiple self‑protection mechanisms such as input undervoltage lockout, over‑temperature shutdown, output over‑voltage protection, and short‑circuit protection. Isolation ratings reach 2250 V (Q48 models) and the devices meet UL 60950‑1, IEC 60950‑1 and other safety standards. Detailed electrical, mechanical, and dynamic specifications are provided for each model variant.
