FEATURES  
DESCRIPTION  
2
•
High Efficiency Step Down Converter  
•
Max Peak Current Limit of 1A, Ideal for USB  
Powered Applications  
The TPS62250 device is a high efficient synchronous  
step down dc-dc converter optimized for USB  
powered applications. It provides up to 1A peak  
output current and limits the average input current to  
700mA, making it ideal for applications connected to  
a USB host. With an wide input voltage range of 2V  
to 6V, the device supports applications powered by  
the USB host as well as general applications  
requiring large output capacitors.

VIN Range Optimized for USB from 2V to 6V  
2.25 MHz Fixed Frequency Operation  
Power Save Mode at Light Load Currents  
Output Voltage Accuracy in PWM mode ±1.5%  
Typ. 15 µA Quiescent Current  
100% Duty Cycle for Lowest Dropout  
Soft Start  
The TPS62250 operates at 2.25MHz fixed switching  
frequency and enters Power Save Mode operation at  
light load currents to maintain high efficiency over the  
entire load current range.  
Voltage Positioning at Light Loads  
Available in a Small 2×2×0,8mm SON package  
Allows <1mm Solution Height  
The Power Save Mode is optimized for low output  
voltage ripple. For low noise applications such as  
USB Wireless Modems, the device can be forced into  
fixed frequency PWM mode by pulling the MODE pin  
high. In the shutdown mode, the current consumption  
is reduced to less than 1µA. TPS62250 allows the  
use of small inductors and capacitors to achieve a  
small solution size.
