• Manufacturer Part Number: LM5072EVAL/NOPB
• Description: EVAL BOARD FOR LM5072
• Manufacturer: National Semiconductor

Specifications of LM5072EVAL/NOPB

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Application Example #3:
Figure 20 shows an application example of the non-isolated version of Figure 18 . This non-isolated version saves many parts
used in the isolated feedback example shown in Figure 18. Similar simplification also applies to the non-isolated version of Figure
19.
Application Example #4
Figure 21 shows an application example of a PD solution using the buck topology. Q2, a dual PNP transistor, is employed in the
output voltage sensing to achieve temperature compensation for the regulated output.
