AHV28XX Series
Application Information
EMI Filter
Inhibit Function
Connecting the inhibit pin (Pin 2 of single and dual models,
pin 8 of triple models) to the input return (pin 10) will cause
the converter to shutdown and operate in a low power
standby mode. Power consumption in this mode is calculated
by multiplying Vin times the input current inhibited, typically
225mW at Vin equal to 28V. The input current inhibited is
relatively constant with changes in Vin. The open circuit
inhibit pin voltage is typically 11.5V and can be conveniently
driven by an open collector driver. An internal pull-up resistor
enables the user to leave this pin floating if the inhibit function
is not used in their particular application. All models use
identical inhibit internal circuits. Forcing inhibit pin to any
voltage between 0V and 6V will assure the converter is
inhibited. The input current to this pin is 500
A maximum at
Vpin2 = to 0V. The converter can be turned on by opening
Pin 2 or forcing a voltage from 10V to 50V. Inhibit pin current
from 10V to 50V is less than ± 50
A.
An optional EMI filter ( AFC461) will reduce the input ripple
current to levels below the limits imposed by MIL-STD-
461 CEO3.
The output voltage of the AHV28XXS can be adjusted
upward by connecting a resistor between the Output
Adjust (Pin 3) and the Output Common (Pin 4) as shown
in Table 1.
