Bourns offering planar transformers handling power upto 70 watts
Date: 02/05/2023
Passive component manufacturer Bourns is offering a planar transformer with output power capability in the range of 48 Watts to 70 Watts. The Model PLN0xx-ED21 Series are forward converter transformers feature high volumetric power density, low loss and and also higher conversion efficiency in a compact, low-height profile design. Compared to wire wound transformers, planar transformers offer higher thermal conduction and heat dissipation making them more reliable, and they also offer lower AC resistance losses.
PLN0xx-ED21 handle input voltages ranging from 33 to 57 VDC and a switching frequency of 250 kHz, feature low leakage inductance from 0.29µH to 0.60 µH and a volt-second time of 81.6 (V-µsec). The series offers 33 V to 57 V input voltage, 5 V to 12 V output voltage at 4 to 14 A output current with different turns ratios. These features and their compact design make Bourns Model PLN0xx-ED21 Series planar transformers ideal power conversion solutions for high density industrial power systems, low profile Switched-Mode Power Supplies (SMPS), LED lighting applications, Battery Management Systems (BMS), PoE applications, and many other forward transformer applications, says Bourns.
Bourns explains these new planar transformers from Bourns use standard PWB material for the transformer windings, soldered to an SMT header to create a simple-to-use, surface mount component that helps ease assembly. In addition, Bourns' custom magnetics product engineers are able to support many modification and customization requests for this planar transformer series.
Bourns Model PLN0xx-ED21 Series planar transformers are available now and are RoHS compliant*. For more detailed product information, please see: www.bourns.com/products/magnetic-products/transformers-planar
