Flex Power Modules adds surface mount version to digital PoL regulator range
The BMR473 is now available in a surface mount format. The digital non-isolated PoL converter has solder bump terminations and is suitable for reverse mounting during reflow-soldering.
The single phase power module measures 19 x 13 x 7.5mm and operates from 6.0 to 15V input. The 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 to deliver 160A output maximum.
Efficiency is up to 96.2 per cent at 12Vin and 5Vout at full load. There is thermal management and a hot spot temperature of 125 degree C maximum.
Features include remote control, a power good signal and configuration and monitoring via PMBus. 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. The modules also includes tight regulation, low output noise and fast load transient response and over 30M hrs MTBF, according to Telcordia SR-332 standard.
The surface mount BMR473 PoL regulator can be used in telecomms and datacomms equipment where automated placement and a low profile in the final form factor are requirements.
