TPS564208 Efficiency question

Other Parts Discussed in Thread: TPS564208

Dear Sir

1. I saw the datasheet of TPS564208 ,17Vin to 1.8Vout/3A's efficiency is better than 5Vin to 1.8Vout/3A's efficiency ,is it correct ??

Generally 5Vin's efficiency should be better than 17Vin's efficiency

2. I think TPS564208 can't support 100%duty ,but figure13 show 5Vin to 5Vout's efficiency

Hi, Kai,

for 5Vin to 5Vo, it's an error, thanks for pointing out, three input should be 9V, 12V, 15V, no 5V input;

for the efficiency, will check RAW data and give you feedback.

Hi, Kai,

yes, you're correct, the RAW data shows Vin = 5V is better than Vin = 15V, it's an error during graph editing by our back end editors, should switch Vin = 5V and Vin = 15V; and also Vin = 9V and Vin = 12V;

Appreciated!
