The TDK Group recently announced the new BCEM series of EPCOS high current chokes designed for buck-boost converters in automotive 48 V power systems. Thanks to the ERU27 ferrite core and flat winding, these innovative SMD inductors are very compact, measuring only 27.5 mm x 29.5 mm x 14.5 mm. The inductor value is 3 μH to 11 μH, its saturation current can be as high as 50 A, and the operating temperature range is -40 ° C to +150 ° C. These components are suitable for switching frequencies from 100 kHz to 200 kHz and are RoHS compliant to meet AEC-Q200 quality certification requirements.

These new components are used as storage chokes in buck-boost converters for 12 V and 48 V power supplies. Using a six- or eight-phase interleaved converter minimizes ripple current and delivers high power levels. Because each converter requires a storage choke, the new high current chokes with compact size and high current values ​​show a strong advantage.
