Austin Series Non-Isolated SMT DC - DC Power Modules:
Output Regulation
These modules have intentional output resistance to facilitate improved transient response and paralleling. This
means that the output voltage will decrease with increasing output current. For this reason, the total DC regulation
window at a given operating and ambient temperature is comprised of a no load setpoint and a voltage drop due to
module output resistance. Regulation data provided in Table 3 includes both the initial setpoint and voltage drop.
Because Table 3 includes output resistance drop, the maximum column is always a no-load condition and the min-
imum column is always a full-load condition. No module could pass production test with a full-load regulation point
equal to the maximum column. This means that at any operating current, the regulation will always be better than
the total window specified in Table 3.
Table 3. Output Specifications
Static Voltage Regulation
The ouput voltage measured at the converter output pins on the system board will be within the range shown in
Table 3, except during turn-on and turn-off. Static voltage regulation includes:

Output Ripple and Noise
Output ripple and noise is defined as periodic or random deviation from the nominal voltage at the output pins
while under constant load and input line. Typical full load output ripple and noise waveforms are shown in
