FEATURES  
DESCRIPTION  
The TPS62590 device is  
a
high efficiency  
2
Output Current up to 1000 mA  
synchronous step down converter, optimized for  
battery powered portable applications. It provides up  
to 1000-mA output current from batteries, such as  
single Li-Ion or other common chemistry AA and AAA  
cells.  
Input Voltage Range from 2.5 V to 5.5 V  
Output Voltage Accuracy in PWM mode ±2.5%  
Typ. 15-μA Quiescent Current  
100% Duty Cycle for Lowest Dropout  
Available in a 2 × 2 × 0.8 mm QFN Package  
For Improved Features Set, See TPS62290  
With an input voltage range of 2.5 V to 5.5 V, the  
device is targeted to power a large variety of portable  
handheld equipment or POL applications.  
The TPS62590 family operates at 2.25-MHz fixed  
switching frequency and enters a Power Save Mode  
operation at light load currents to maintain a high  
efficiency over the entire load current range.  
APPLICATIONS  
Portable Handheld  
WLAN  
Low Power DSP Supply  
POL  
The Power Save Mode is optimized for low output  
voltage ripple. For low noise applications, 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 1 µA.  
The TPS62590 allows the use of small inductors and  
capacitors to achieve a small solution size.  
The TPS62590 is available in a 2-mm × 2-mm 6-pin  
QFN package.
