Murata’s newest product releases, which will be best-positioned for new product designs requiring a single output, are showcased in this slide. Note that all of these products carry an isolation rating of 2.25kV. The reason for the increase was to accommodate one additional application for Power-Over-Ethernet (PoE), which carries this higher isolation requirement. In addition to isolation, all these products also share a common operating temperature range of -40°C to 85°C, although the various models and series have unique temperature de-ratings. The UHE offers the widest array of input and output combinations of any Murata series available. These converters have 2:1 and 4:1 input ranges, with all of the digital and analog output voltages from 1.2V to 15V available. The UHE series comes in the standard 1.6” x 2” package with a plastic case. The next three series are all designated as UEI, or Unipolar Extended Input range. The extended input range simply means 4:1, so all models are designated as either Q12 or Q48 with corresponding ranges. Beyond the family designation of UEI, these units actually share little else. The UEI15 is a 15W product in a 1" x 1" form factor. It essentially replaces most UWR products with a lower cost, higher power density solution with a wider 4:1 input range. There are a couple of things to watch out for if recommending this product for a cost reduction over an existing UWR solution. The first is that the UEI series is available only with the trim pin and the remote on/off control pin. While some existing 1” x 2” products have these pins, others may not. So drop-in replacement may not always be possible using the UEI15. Secondly, the UEI15 is available only with a plastic case. Thus, in applications where radiated EMI is a concern, the unit will have to be tested in the application to determine if the emissions are acceptable. The UEI30 delivers up to 30W in a 1” x 2” package. This product has the same pinout as the “External Pin-out” of the UEP series, and thus replaces that. This is the same pin configuration as shared by most 1.6” x 2” products, such as the UHE and the WPN20. Thus, with as much or more power as the UHE, WPN20, and UEP, the UEI30 can replace most of these at a lower cost. The only issues that my preclude this is the more limited output voltages (as compared to the UHE), the lack of the remote sense option, and the open frame construction. For customers desiring these features, one of these other series may be more appropriate. For new designs, the UEI30 will be much more cost-competitive. Lastly, the UEI series has the same mixed signal output voltages as the UEI15 and UEI30 3.3V, 5V, 12V, and 15V versions. As previously noted, the lower purely digital output voltages below 3.3V are more effectively provided through the use of a non-isolated POL (point of load) supply like the Okami series. The UEI series is a drop-in replacement to the UHE 1.6” x 2” platform, providing up to twice the power in the same footprint.
