The BXA3 Series of DC/DC converters is designed to offer the optimum
cost/benefit power solution for a wide variety of applications including public
and private telecommunications, industrial systems and process and test
equipment. The series consists of 9 models with input voltages of 9-18VDC, 18-
36VDC and 36-75VDC, and offers standard output voltages of 3.3V, 5V, 12V and
15V in single and dual output configurations. Continuous short circuit protection,
overvoltage protection, 60mV output ripple and EN55022 level A conducted
noise compliance minimize design-in time, cost and eliminate the need for
external components.
