EXB30 SERIES Dual positive output * * * * * * * * * * 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.
