The new product delivers a flexible solution in a small package, addressing multiple design headaches for the customers
Flex Power Modules introduces the BMR469 family, a digital point-of-load (PoL) regulator that is ideal for high-current ICT applications. It delivers high power density, up to 160A per square inch, which saves valuable board space.
2 variants with different output currents are available, both in compact packages. The 80A BMR4690000 measures 25.4 x 12.7 x 11.6mm (1.00 x 0.50 x 0.46in), while the 50A BMR4696001 provides a low-profile solution with a maximum height of just 5.8mm (0.23in). The low height of the BMR4696001 also makes it possible to place it very close to the processor, thus improving transient response.
Both versions are configurable as either dual outputs or a single, higher-power output. This gives customers the flexibility to use one part to cover different requirements, for example to drive different processors or FPGA rails, helping simplify power system design.
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 4 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. The regulator is also supported by a simulation model in Flex’s Power Designer software, making design and debug work straightforward.
The BMR469 is well suited to a broad range of applications in the ICT sector, and in particular is ideal for designs that require high power density and a digital architecture solution, such as test equipment or simulator manufacturers. It is capable of providing sufficient power to drive high-end components such as processors, FPGAs and ASICs.
- High efficiency: typically 92.6% at half load (12Vin, 5Vout)
- Input voltage range is 7.5V to 14V
- Output range is 0.6V to 5V
The BMR4690000 is available now, and the BMR4696001 will be available in April 2019
