BXA75-48S3V3

BXA75 SERIES Single output • • • • • • • 3.5 x 2.4 x 0.5 inch package with stand-offs 19 Watts/in3 power density Efficiency up to 87% CISPR 22 and EN55022 conducted emissions level A UL, VDE and CSA safety approvals Indefinite short circuit protection Baseplate operating temperature range of –25°C to +85°C [ 2 YEAR WARRANTY ] The BXA75 series are high density DC/DC converters ideally suited for a wide variety of communications, industrial, computer and distributed power applications. With up to 80 Watts of power in a 3.5 x 2.4 x 0.5 inch package and efficiencies as high as 87%, the BXA75 can address a host of demanding power requirements, offering a wide input range of 36-75VDC with industry standard outputs of 3.3V, 5V, 12V and 15V. Approval to EN60950 and EN41003 coupled with conducted emissions compliance to CISPR 22, FCC and EN55022 level A, facilitate easy and cost effective design-in for communications systems. The demands of industrial systems are met by a baseplate operating temperature range of –25°C to 85°C, overvoltage, overtemperature and short circuit protection, along with tight load and line regulation and output ripple as low as 15mV rms. Other standard features include remote enable, remote sense and external trim.
