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