It is also suitable for reverse mounting during reflow-soldering.

The mechanical module measures 19 x 13 x 7.5mm and operates from 6.0 to 15V input. Regulated output is adjustable from 0.6 to 5.0V at up to 40A. Up to four units can be paralleled with synchronisation and phase-spreading for a maximum of 160A output.

The single phase power module has efficiency up to 96.2% at 12Vin and 5Vout at full load. Minimal temperature derating is required due to thermal management and a 125°C maximum hot spot temperature, advises Flex.

Remote control, a power good signal and configuration and monitoring via PMBus are included and the module is compatible with the Flex Power Designer GUI.

There is also input under- and over-voltage, over-temperature and output over-voltage, over-current and short-circuit protection. In addition, there is tight regulation, low output noise and fast load transient response and over 30M hrs MTBF, according to Telcordia SR-332 standard.

The surface mount version of the BMR473 PoL regulator will be useful to customers in telecomms and datacomms sectors who require automated placement and a low profile in the final form factor.
