Wide 4:1 input DC/DC converters deliver 30W from 1in. x 2in. package

UEI30 isolated wide-range DC/DC converters deliver a full 30W output power from a board area of just 1.8 square inches. Designed for PCB mounting, the new modules deliver efficient DC regulated power and are ideal for use in both battery and mains powered equipment in applications requiring wide input voltage, such as small instruments, computer-based systems, datacoms equipment, remote sensor systems and vehicle electronics.

The UEI30 series comprises eight input/output combinations giving tightly regulated fixed output voltages of 3.3, 5, 12 and 15VDC and a choice of 4:1 inputs of 9 to 36VDC or 18 to 75VDC. A synchronous rectifier forward topology helps the UEI30 series achieve high efficiency levels of up to 91% and minimal heat build-up allowing operation without cooling fans.

• Industry standard open-frame package and pinout
• Efficiency levels up to 91%
• 3.3VDC to 15VDC fixed output voltages
• Choice of 9 to 36VDC and 18 to 75VDC input voltages
