Output Voltage
(Over all operating input voltage, resistive load,
and temperature conditions until end of life; see
Figure 13.)
Output Voltage Set Point
(VI = 28 V; IO = IO, max; TC = 25 °C)
Output Regulation:
Line (VI = 18 V to 36 V)
Load (IO = IO, min to IO, max)
Temperature (TC = –40 °C to +100 °C)
Output Ripple and Noise Voltage
(See Figure 12.):
RMS
Peak-to-peak (5 Hz to 20 MHz)
External Load Capacitance (electrolytic)
Output Current
(At IO < IO, min, the module may exceed output
ripple specifications.)
Output Current-limit Inception
(VO = 90% of VO, nom)
Output Short-circuit Current (VO = 250 mV)
Efficiency (VI = 28 V; IO = IO, max; TC = 70 °C)
Dynamic Response
(∆IO/∆t = 1 A/10 µs, VI = 28 V, TC = 25 °C):
Load Change from IO = 50% to 75% of IO, max:
Peak Deviation
Settling Time (VO < 10% of peak deviation)
Load Change from IO = 50% to 25% of IO, max:
