Allegro Microsystems has today introduced a new series of POL converter modules, the BR200 series. Featuring an industry standard exterior shape and footprint, these new thin-profile POL converters are responsive to very high speed loads and are also compatible with ceramic capacitors. Typical applications for the BR200 series include router switch equipment and WDM computer server applications within the telecommunication server market.

Designed with higher efficiency and an increased power density, the new BR200 series POL converters are offered in a thinner package that most competitive solutions on the market today. Allegro’s new devices can be used as design-free POL converters for a 5 V or 12 V system intermediate bus and are easily configured, allowing a reduction in overall design time and the reuse of designs.

Miniaturization was achieved by high frequency switching technology, to save space on the application PCB. Soldering capability has been significantly improved by adoption of end face through holes.

The use of high frequency switching technology allowed for miniaturization to be achieved, resulting in space-saving on the application PCB. The implementation of end face through holes has considerably improved soldering capability.
