AME5125-High Efficiency 500KHz Step-Up Converter 
DataSheet
DESCRIPTION
The AME5125 is a high-performance current mode synchronous
boost converter with integrated Power MOSFETs
which on-resistance of internal main switch is only 50mW
and rectifier switch resistance is 50mW to maintain high
efficiency in heavy load conditions that supports switch
peak current of up to 5.5A. The integrated circuit supports
an input voltage range of 2.7V to 5.5V.
The converter can be disabled to minimize battery drain.
During shutdown, the load (VOUT) is completely disconnected
from the battery (VIN). Additional functions include
an internal soft-start function in order to easy inrush
current control. The circuit protection includes Over
Voltage Protection and Thermal Shutdown to prevent device
failure under the "Worst" of operating conditions.
This device is available in SOP-8/PP with exposed pad
for low thermal resistance.
