NDY Series
Isolated 3W Wide Input DC/DC Converters
APPLICATION NOTES
Recommended input & output capacitors
Although these converters will work without external capacitors, they are necessary in order to guarantee the full parametric performance over the full line and load
range. All parts have been tested and characterized using the following values and test circuit.
Input Voltage
5V, 12V
24V, 48V
C IN
100μF, 25V (0.25Ω at 100KHz)
10μF, 100V (1.5Ω at 100KHz)
Output Voltage
3.3V
5V, 12V, 15V
C OUT
100μF, 25V (0.25Ω at 100KHz)
L OUT
MPS# - 24100C

Output load
The minimum rated load across the whole input voltage range is 25% of the full load output. It is important to take care that the load does not fall below this as the output ripple
will greatly increase. While this condition will not harm the device the resultant increase in output ripple could cause customers’ application to malfunction.
