AME5110
n General Description
Synchronous Buck, DC-DC Converters, apply the latest
innovations in Current-Mode Technology. Available in SOT-
25 package, these devices are typically twice as efficient
as standard LDO’ s, making them well suited for most
portable applications.
LDO’ s,(1) Input, and (1) Output capacitor are required.
The only other element is a small, low cost, 2.2 H induc-
tor. The AME5110 is availabe with fixed output voltages
of 1.5V and 1.8V, or adjustable at 600mA. Using a propri-
etary “ Extreme Green” Technology, battery life is maxi-
mized with Frequency Foldback at light Load, and 100%
duty when Vin approaches Vout.
