After verification, the BMR466 achieves a power density of 24A/cm3, and at an input voltage of 5V and an input voltage of 1.8V, the efficiency is as high as 94.4% at half load. The module can handle currents up to 60A, designed for complex circuit boards Designed for powering microprocessors, FPGAs, ASICs and other digital ICs. In addition, engineers can connect up to eight such fully-regulated 60A (max) POL converters in parallel in multi-module and multi-phase systems. Provides up to 480A of current. The BMR466 has an input voltage range of 4.5V to 14V and is ideally suited for operation over a wide range of intermediate bus voltages and is compliant with the dynamic bus voltage scheme to reduce power consumption and save energy. The factory default output voltage is set to 1.2. V, but can be adjusted within the range of 0.6V to 1.8V using pin-setting resistors or PMBus commands.
The BMR466 is software controlled and uses advanced PWM control loop adaptive compensation and advanced energy optimization algorithms to reduce energy consumption and provide stable and reliable power supplies with fast transient performance over a wide range of operating conditions. In this case, two or more single-phase BMR466 POL converters can be phase-synchronized with an external clock, which means that input ripple current and corresponding capacitance requirements and efficiency losses can be reduced.
Introduced in 2013, the BMR461 is the first 12mm x 12mm x 8mm 12A digital POL module for power reduction, combining dynamic loop compensation (DLC), low bias current technology and advanced energy optimization algorithms. The DLC is based on 'state space' or 'model prediction' controls to ensure stability while also achieving optimal dynamic performance without any external components.
The BMR461's input voltage range is also 4.5V to 14V; Efficiency is Significantly Improved - Especially in modules below 1V, performance is 10% higher than typical high-end devices. For example, the BMR461 takes power from the 5V intermediate bus , Designed for use in 0.6V applications, it is proven to be 85.7% efficient at full load, whereas conventional devices that do not use low bias current technology have a typical efficiency of only 75%. Or, when the intermediate bus With a voltage of 12V and an output setting of 5V, the BMR461 achieves 96% efficiency at 80% load.
Both the BMR461 and BMR466 are designed and manufactured by Flex to meet the industry's highest standards for DC/DC power converters, providing power system designers with the level of quality and confidence needed to develop long-term, high-performance platforms.
Two BGA and LGA versions of the BMR461 and BMR466 are now in volume production and are available in OEM quantities.
