3W Wide Input DC/DC Converters 1
3 Watts in DIL Package 9 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 -25C to +105C 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 9 models with input voltages of 9-18VDC, 1836VDC 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.
2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25C unless otherwise stated

Notes
1 2 3 4 5 Maximum. Maximum figure at full load (nominal). Low line to high line. Full load to no load. 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. BXA3-12S15-F. Conducted noise filtering to EN55022 level B may be accomplished by putting the following capacitors across the input pins. 12VDC 5F ceramic X7R dielectric type 24VDC 3F ceramic X7R dielectric type 48VDC 1F ceramic X7R dielectric type 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.
