Dear All:

ADP2503/ADP2504 SYNC pin how can control is very energy efficient? My ADP2504 SYNC pin need MCU GPIO to control It. maybe long time at pull-down but some times need at pull-up. so can you tell me the R1/R2 best resistance value is how much?  the SYNC can work normally Pull up and pull down  in the power save system. Another Pin 10 (FB) leakage current  is ?uA, if i use ADP2503ACPZ-R7 (ADJ Mode) R3/R4 how to select it? is Mega ohm more power save? have any suggestions provide to me refer. thanks

 

 

Best Regards,
Jacky
