Refer to application notes on website for external circuitry and PCB layout.

(1) Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used, the +Sense and - Sense should be connected

to their corresponding outputs; + output, -output.

(2) Dual and Triple output models require a minimum load of 10% on the output to maintain speciﬁed regulation. No load operation will not damage the device.

(3) Load regulation for triple output: Main output:10-100%, with 10-100% balanced load on auxiliaries. Auxiliary outputs: 10% to 100% balanced on all outputs.

(4) Cross regulation for dual output: asymmetrical load 25% / 100% full load. Cross regulation for triple output: Main output 100% load, auxiliary 100%, other

auxiliary 25% to 100%. Auxiliary outputs: main output 100% load, auxiliary 100%, other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other

auxiliary 25% to 100%.

(5) Simulated Source impedence of 12uH placed in series with + input.
