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.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
