Input Characteristics:

Unless otherwise specified, specifications apply over all rated Input Voltage, Resistive Load, and Temperature conditions.

Characteristic Min Typ Max Unit Notes & Conditions

Operating Input Voltage 4.5 --- 14 Vdc

Maximum Input Current --- --- 20 A Vin=4.5 to Vin,max; Io=Io,max

Startup Delay Time from application of input voltage --- 5 --- mS Vo=0 to 0.1*Vo,set; on/off=on,

Io=Io,max, Tc=25˚C

Startup Delay Time from on/off --- 5 --- mS Vo=0 to 0.1*Vo,set; Vin=Vi,nom,

Io=Io,max,Tc=25˚C

Output Voltage Rise Time --- 4 --- mS Io=Io,max,Tc=25˚C, Vo=0.1 to

0.9*Vo,set

Input Reflected Ripple --- 15 --- mApp See input/output ripple measurement

figure; BW=20 MHz

Input Ripple Rejection --- 45* --- dB @ 120 Hz

*Engineering Estimate

Caution: The power modules are not internally fused. An external input line normal blow fuse with a

maximum value of 20A is required, see the Safety Considerations section of the data sheet.

Characteristic Min Max Unit Notes & Conditions
