Isolated 3W Wide Input Dual Output DC-DC Converters

Unspecified 

NDT SERIES

Isolated 3W Wide Input Dual Output DC-DC Converters

TERMINOLOGY

LINE REGULATION

The percentage change in output voltage between low input voltage and high input voltage,

measured with fixed output load

ie. A 5V output part with an output voltage of 5.05V @ high input voltage and 5.03V @

low input voltage would have a line regulation of 0.4%.

line regulation = VOUT (Low Input V) –VOUT (High Input V) x100%

VOUT (Nominal Input V)

Where VOUT (Nominal Input V) is 5V.

APPLICATION NOTES

EXTERNAL CAPACITANCE

Although these converters will work

without external capacitors, they ar e

necessary in order to guarantee the full

parametric performance over the

full line and load range. All parts have

been tested and characterised

using the following values and test circuit
