SNVS655I June 2011 – January 2016 LM5066
Table 1 summarizes the differences between the LM5066 and the LM5066I. Note that the current monitoring accuracy of the LM5066I is much better at the ILIM = 26 mV setting, but is comparable at the 50-mV setting. For many applications with lower power, using the LM5066 at the 50-mV setting is a great option. However, for higher power applications upgrading to LM5066I and using the ILIM = 26 mV setting will lead to significant power savings (approximately 24 mV × ILOAD). In addition, the higher accuracy and energy monitoring capability can enable further improvements in system efficiency, which is critical in high power applications.
