The BMR453 packs up to 396W (or 60A) into a Quarter Brick package measuring just 57.9mm x 36.8mm, and is available either as an open frame package for low profile, convection cooled applications, or mounted with a baseplate for conduction cooling to a suitable heatsink or cold wall. Factory preset output voltages are available from 3V to 13V, and efficiencies are as high as 96%. In addition, the Eighth Brick BMR454 offers up to 240W (or 40A) in a 58.4mm x 22.7mm package with similar performance figures.
Both families accept the Telco standard 2:1 Input Voltage range of 36-75V, and have a standard operating temperature range of -40degC to +125degC (case). Safety features such as Over Current, Over Voltage and Over Temperature protection are included, as well as continuous Short Circuit protection. An energy saving Remote On/Off function is also included as standard.
