Product Highlights

•

HEHB Family of dc-dc converters is

Magnetek’s solution for next generation,

cutting-edge board applications.

•

Synchronous rectification uses MOSFET

instead of Schottky diodes providing

extreme reduction in heat generation,

boosting efficiency, eliminating the need for

a heat sink and increased reliability.

Low profile (0.44”), open frame construction

allows smaller card pitch and improves

system ventilation.

•

Fixed switching frequency provides

predictable EMI characteristics.
