* This series of products using reduced frequency technology, the switching fre-

quency is test value of full load. When the load is reduced to below 50%, the

switching frequency decreases with decreasing load.

* 0%-5% load ripple & noise is no more than 5%Vo. Ripple & noise are measured

by ”parallel cable” method, please see DC-DC converter application notes for

speciﬁc operation.
