[ 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.

Notes
1 At nominal input and output voltage and maximum load.
2 Total error band is defined as the static output regulation at 25°C including
initial setting accuracy, input voltage within stated limits and output
current within stated limit.
3 Measured with 10µF tantalum capacitor across output.
4 EMI measured on either line into a 50LISN with 120µF electrolytic input
capacitor.
5 Overvoltage limit may be tested by applying -5V to -15V to the trim pin 11
with respect to –sense pin 18.
6 To order optional standard heatsink, please add suffix ‘-1’ to model
number e.g. BXA75-48S05-1.
