BXA3 Series

Single and dual output

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.

All specifications are typical at nominal input, full load at 25°C unless otherwise stated
