EXB30 Series Dual positive output DC/DC CONVERTERS • • • • • • • • • • 30W High Efficiency DC/DC Converters 1 Two independent positive outputs Output voltage tracking High efficiency Approved to EN60950, UL1950, CSA C22.2 No. 950 Operating ambient temperature of -40°C to +70°C (natural convection) Up to 100% load imbalance Separate trim on each output No minimum load Complies with ETS 300 019-1-3/2-3 Fully compliant with ETS 300 386-1 The EXB30 Dual series are isolated dual positive-output DC/DC converters. The products are designed using a high-efficiency synchronous rectification topology. They feature two independent fully regulated outputs, which are individually trimmable. The EXB30 Dual employs Dynamic Current Allocation such that maximum current can be drawn from either output with a total output current capability of 6A. No minimum load is required for either output. In addition, these products incorporate a tracking feature such that both outputs rise together with their output differential never exceeding 0.7 Volts during start-up. A remote on/off and latching overvoltage protection for both outputs are included as standard. These latches are enabled by default, but can be disabled by the user. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25°C unless otherwise stated OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability Both outputs ±11% min.
