Flex Power Modules' Dual-Output Digital Pol Regulator Serves High Power-Density ICT Apps
March 26, 2019
Flex Power Modules introduced the BMR469 family, a digital point-of-load (PoL) regulator that is suitable for high-current ICT applications.
Flex Power Modules introduced the BMR469 family, a digital point-of-load (PoL) regulator that is suitable for high-current ICT applications, with a power density of up to 160A per square inch.
Two variants with different output currents are available, the 80A BMR4690000 (25.4 x 12.7 x 11.6mm), and the 50A BMR4696001 (with a maximum height of 5.8mm), making it possible to place it very close to the processor.
Both versions are configurable as either dual-output or a single, higher-power output.
The BMR4690000 variant provides two independent 40A outputs for dual configurations, or one 80A rail in single-output operation mode, while the BMR4696001 provides 2 x 25A outputs or one 50A rail in single-output operation mode. Up to four modules can be paralleled for current sharing, delivering a total of up to 320A for the BMR4690000 and 200A for the BMR4696001.
The BMR469 is simple to configure via pin-strap or PMBus, making it easy to set up for different applications. The regulator is also supported by a simulation model in Flex’s Power Designer software, making design and debug work straightforward.
Efficiency is typically 92.6 percent at half load (12Vin, 5Vout). The input voltage range is 7.5V to 14V, and output range is 0.6V to 5V. The BMR469 meets safety requirements according to IEC/EN/UL 62368-1, and offers a mean time between failures (MTBF) of 18.49 million hours.
