Parameter
Output Voltage Set Point
(VI = 48 V; IO = IO, max; TC = 25 °C)
Output Voltage
(Over all operating input voltage, resistive load,
and temperature conditions until end of life.
See Figure 10.)
Output Regulation:
Line (VI = 36 V to 75 V)
Load (IO = IO, min to IO, max)
Temperature (TC = –40 °C to +100 °C)
Output Ripple and Noise Voltage
(See Figure 9.):
RMS
Peak-to-peak (5 Hz to 20 MHz)
External Load Capacitance
Output Current
(At IO < IO, min, the modules may exceed output
ripple specifications.)
Output Current-limit Inception
(VO = 90% of VO, nom)
Output Short-circuit Current (VO = 250 mV)
Efficiency (VI = 48 V; IO = IO, max; TC = 70 °C)
Switching Frequency
Dynamic Response
(ΔIO/Δt = 1 A/10 µs, VI = 48 V, TC = 25 °C;
tested with a 10 µF aluminum and a 1.0 µF
ceramic capacitor across the load):
(see Figures 5 and 6)
Load Change from IO = 50% to 75% of IO, max:
