Notes
1 Measured with 10µF tantalum capacitor and 0.1µF ceramic capacitor
across output.
2 di/dt = 1A/1µs, Vin = 48VDC, Tc = 25°C, load change = 0.5 lo max. to 0.75
lo max. and 0.75 lo max. to 0.5 lo max.
3 Units should be characterised within systems. External components
required.
4 Input fusing is recommended based on surge current and maximum input
current.
5 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6 Simulated source impedance of 12µH.
7 Option with active high remote on/off (standard product is active low) is
available. Designate with the suffix ‘FH’, e.g. BXB75-48D05-3V3FH.
BXB75-48D3V3-2V5FH is not available.
8 Start-up in resistive load.
9 5V at 15A.
10 Measured with 15A load on 3.3V output and 5A load on 2.5V output.
11 Numbers in brackets refer to output 1.
12 Combined maximum output current that may be drawn from both channels
simultaneously is 20A (i.e. current from OP1 + current from OP2).
13 Connect input to case when performing hipot test from output to case.
14 1A minimum load required on the higher voltage output.
