BXA10 SERIES Single and dual output * * * * * * The BXA10 series of DC/DC converters, comprising 15 different models, is designed for a wide range of applications including communications, industrial systems and mobile battery powered systems. Packing up to 10 Watts of power into a 2 x 1 x 0.395 inch package, with efficiencies as high as 85%, the BXA10 has wide input ranges of 9-18VDC, 18-36VDC, 18-75VDC and 36-75VDC, and is available in single and dual output versions. Isolation of 1500VDC, approval to EN60950 2nd edition, coupled with reduced conducted noise for simplified compliance to FCC Part 15 level A and EN55022 level A, make the BXA10 ideal for telecommunications and distributed power applications. Other features include overvoltage protection, continuous short circuit protection with automatic recovery and remote on/off, all of which minimize the need for external circuitry and make the BXA10 a recommended component in distributed power systems.

Output ripple can be reduced to <50mV with the addition of a 33F, 25V, AVX-TPS (or equivalent) tantalum capacitor. Consult factory for further information. For units with optional remote ON/OFF, please add the suffix `-S' to the model number: e.g. BXA10-48S05-S. Maximum open pin voltage 14VDC. Assumes balanced loads on dual output models. High impedance source/long input power cable may necessitate the introduction of an input filter. Typical 9-18VDC model start-up voltage is 9V. Maximum start-up voltage is 9.5V (>0C) or 9.7V (<0C). It is recommended that an IEC127, 250V, fast blow fuse is used rated at 4A for nominal 12V models; 3A for nominal 24V models and 2A for 48V models. To achieve compliance to EN55022-A and FCC part 15 Class A, external capacitors of the following values are needed: Model BXA10-12xxx BXA10-24xxx BXA10-48xxx C1* 10F film, 25V 10F film, 50V 10F film, 100V C2 0.22F film 0.22F film 0.22F film NUMBER (3) LINE PIN CONNECTIONS PIN NUMBER SINGLE OUTPUT DUAL OUTPUT 1 +Vin + Vin 2 - Vin - Vin 3 + Vout + Vout 4 No Pin Common 5 - Vout - Vout 6* Remote ON/OFF Remote ON/OFF 5 * Optional remote ON/OFF pin.
