NDTS Series

Isolated 3W Single Output DC/DC Converters

APPLICATION NOTES (continued)

Minimum Load

The minimum load for correct operation is 25% of the full rated load across the specified input voltage range. Lower loads may cause a significant increase in output ripple and

may cause the output voltage to exceed its specification transiently during power-down when the input voltage also falls below its rated minimum.

The following graphs show the typical required minimum load required for stable operation in mA verses input voltage. Some variants are not included as they do not typically

require a minimum load for stable operation: NDTD1212C, and NDTD1215C.

The NDTS series will operate from a wider input range than specified in the input characteristics datasheet table with output power derating. Please contact Murata Power
