Compact regulated and isolated 9 W DC-DC converters offer 4:1 input range

XP Power has announced the ITZ series of compact regulated 9 Watt DC-DC converters. Believed to be the smallest 9 W DC-DC converters currently on the market, the units accommodate an ultra-wide 4:1 input and are available with single and dual outputs.

The series has been packaged in an ultra-compact metal case measuring 21.9 x 11.2 x 9.6mm and the converters are up to 89 % efficient and have a power density of 44 Watts per cubic inch. This level of efficiency means that no additional heat sink components or forced airflow is required, ensuring that the converter occupies the smallest footprint possible, which is essential for space constrained designs.

The series offers two 4:1 input range options of either + 9 to + 36 VDC or + 18 to + 75 VDC, covering all the popular nominal input voltages of + 12, + 24 and + 48 VDC. Single output models are available with + 3.3, + 5, + 9, + 12, + 15, or + 24 VDC. Duals provide +/- 5, +/- 12 or +/- 15 VDC. No minimum load is required.

Input to output isolation is rated at 1.5k VDC across the range, and optionally, 3k VDC isolation is available on –H models. Suitable for most environments the ITZ series can operate across an extended temperature range from – 40 to + 85°C and deliver the full output power up to +60°C. A remote on/off function provides the ability to externally control the converter such as for sequencing start-up or automatically powering it on or off.

All model meets EN55032 level A for conducted and radiated noise without any additional components.

Typical applications for the ITZ series include mobile, portable and wireless products, and any low power use case where isolation and DC voltage conversion is required.
