AME AME5110AEEV180Y 600ma / 1.2mhz pwm buck dc-dc converter Datasheet

AME, Inc.
600mA / 1.2MHz PWM
Buck DC-DC Converter
AME5110
n General Description
The AME5110 family of Fixed Frequency,High Efficiency,
Synchronous Buck, DC-DC Converters, apply the latest
innovations in Current-Mode Technology. Available in SOT25 package, these devices are typically twice as efficient
as standard LDO’ s, making them well suited for most
portable applications.
The AME5110 is simple to use. As with standard
LDO’ s,(1) Input, and (1) Output capacitor are required.
The only other element is a small, low cost, 2.2µH inductor. The AME5110 is availabe with fixed output voltages
of 1.5V and 1.8V, or adjustable at 600mA. Using a proprietary “ Extreme Green” Technology, battery life is maximized with Frequency Foldback at light Load, and 100%
duty when Vin approaches Vout.

Pin Description
Enable Control Input.
Forcing this pin above 1.5V enables the part. Forcing this
pin below 0.3V shuts down the device. In shutdown, all
functions are disabled drawing <1µA supply current.
Do not leave EN floating.
