The PQ60120HZA50 DC/DC converter measures only 61x58.4x10.5mm in an open-frame format, delivering a regulated output of 12V up to a maximum rating of 50A from the full telecom input-voltage range of 35 to 75V. Targeting IBAs (intermediate bus architectures), the device makes use of the latest high-performance components to delivers the maximum 50A rating at up to 95% efficiency. Half-load efficiency performance is even greater at 96.5%. For extended-temperature operation, or to provide the full 600W rated power of the device, an optional encased unit is also available to enable the use of a heatsink or for attachment to a cold plate. The converter is capable of withstanding transients on the input to 100V for 100ms and has a basic isolation level from input to output of 2250Vdc. Control and protection features include remote sense, an ultra-wide output-voltage trim range of -50 to +5%, input under-voltage lockout, output OVP, current limit, short-circuit protection, and thermal shutdown. Operating-temperature range is -40 to +100°C. The unit is also fully RoHS 6/6-compliant. Sample and production quantities are available immediately with a stock to 12-week lead time.
