thanks, thats 1.05, the gen6 simulator i had was 1.02. seems like citi's US division lag behind the other regions. will be interesting to test, the simulator actually shows 1212 as more efficient below 500 mA but once you get to 700 and above the 1216 pulls away (esp above 2000 mA
even at 1400 mA there is advantages. significant bump in thermal management and efficiency but what i really like is the solid 1V drop in voltage- thats gonna open up more driver options for sure where the 1212 was tight
i was never a big fan of the 1812 even though it was the closest match to a cxb, as its higher number of dies in series dipped the efficiciency a bit (relative to the similar voltage 1818, the 1812 is still better than 1212 watt for watt). this 1216 is about the same performance as 1812 at a given wattage and should fill the gap nicely and at 36V (34V!) taboot.
you can see the big impact die arrangement has on voltage. 1812 is too high to work well with the popular 48A drivers. 1818 is better on voltage and 1825 better yet
a 1218 would have been most excellent but im sure they have their reasons, one of the features touted in the datasheet is improved die layout maybe thats how theyre getting the bump in thermal performance
id probably elect to phase out the 1212 in favor of 1216 eventually. citi has too many options, i just want to stock the best model in 36V, the best model in 50V, etc.
