BXA3 SERIES
Single and dual output
[ 2 YEAR WARRANTY ]
• 3 Watts in DIL Package
• 21 models including 3.3VDC output
• Wide input ranges 9-18V, 18-36V, 36-75V
• EN55022 conducted emissions level A (optional)
• Continuous short circuit protection
• Operating temperature range -25°C to +105°C
• Input voltage range to ETS300-132-2
• UL, VDE and CSA safety approvals
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 21 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 both 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.
SPECIFICATION
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

2 Maximum figure at full load (nominal).
3 Low line to high line.
4 Full load to no load.
5 An optional internal filter is available. When the filter is added, the BXA3
will meet VDE0871-A, VDE0878-A and EN55022-A. Add the suffix ‘-F’ to
the model number, e.g. BXA3-12D12-F.
6 Conducted noise filtering to EN55022 level B may be accomplished by
putting the following capacitors across the input pins.
12VDC 5µF ceramic X7R dielectric type
24VDC 3µF ceramic X7R dielectric type
48VDC 1µF ceramic X7R dielectric type
7 Reverse voltage protection can be implemented by putting a fast blow
fuse on the positive input rail. Rate the fuse for 250mA at 48VDC input,
500mA at 24VDC input and 1000mA at 12VDC input.
