Typical at TA = +25°C under nominal line voltage and full-load conditions, unless otherwise
noted. All models are tested and specied with external 33F capacitor installed across their
input and output pins.
Ripple/Noise (R/N) is tested/specied over a 20MHz bandwidth.
These devices have no minimum-load requirements and will regulate under no-load conditions.
Regulation specications describe the output-voltage deviation as the line voltage or load is
varied from its nominal/midpoint value to either extreme.
M E C H A N I C A L
S P E C I F I C A T I O N S
Nominal line voltage, no-load/full-load conditions.
The operating input voltage is 10.2V to 13.8V. However, 10.8VIN is required for the DC/DC
to properly start up under all line, load and temperature conditions. The 10.8V potential must be
maintained across the inputs until the output is up and regulating. After the output is regulating,
the operating input range is 10.2V to 13.8V.
