Electronics Power Supply / Management brick converter dc-dc digital quarter

FLEX POWER MODULES BMR684 through-hole mounted 700W digital quarter brick dc-dc converter is targeted at RFPA applications needing a 50V supply at up to 14A for gallium nitride (GaN) or laterally diffused MOSFET (LDMOS) power amplifiers, and a wide adjustment range of 25-55V is offered to help system designers achieve the optimum efficiency and linearity of the power amplifier.  Device achieves an impressive 96% efficiency at full load, and has a maximum baseplate operating temperature of 100°C. The converter input range is 36-75Vdc and a remote-control function is included, along with remote sense. Input-output isolation is 1500 Vdc, and the device is packaged in the industry-standard quarter brick format measuring 58.4 x 36.8 x 12.7mm.
