The EXB50 Dual is a 50W independently regulated dual output DC/DC converter specifically designed to meet the power needs of low voltage silicon. Housed in an open frame package with an industry standard 1/2 brick footprint, the EXB50 Dual can deliver up to 8.5A from either output, and up to 11A in total, at temperatures of up to 70C under natural convection. With some forced air and/or reduced ambient temperatures, the EXB50 can deliver up to 8.5A from either output, and up to 17A in total. The converter is primarily intended for the networking, telecoms and wireless markets, where small size, lower output voltages with higher currents, low profile and high efficiency are all key demands. Product features include wide output trim and remote on/off. Overvoltage, short circuit and over-temperature protection combines to make the EXB50 Dual a very robust and flexible product.
All specifications are typical at Vin = 48V, Io1 = 5A, Io2 = 5A, Tamb = 25C unless otherwise stated

Latching OVP response time is 2ms (typ.). OVP latch is reset by toggling the control input, or by cycling the input voltage. User must provide recommended fuses in order to comply with safety approvals. Meets both level A and level B conducted emissions only with external components connected before the input pins to the converter. Maximum temperature on hotspots not to exceed 110C. See Application Note 127 on Artesyn Technologies website www.artesyn.com. See the long form data sheet for derating curves. For stable operation connect an external output capacitor of at least 100F to each output. Recommended capacity AVX TPS series (e.g. TPSD107*010#0100) or equivalents. Active low remote ON/OFF, is available. Standard product is active high. Designate with the suffix `-R' e.g. EXB50-48D05-3V3-R. Maximum total current from the module is 15A for EXB50-48D05-3V3 and 17A for EXB50-48D3V3-1V8 with airflow.
CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is not user accessible.
