2.25-MHz, 600-mA Step-Down Converter in TSOT and 2- × 2- × 0,8-mm SON Package  
With a wide input voltage range of 2.5 V to 5.5 V, the  
devices support applications powered by Li-Ion

High-Efficiency Step-Down Converter  
batteries with extended voltage range, two- and  
three-cell alkaline batteries, 3.3-V and 5-V input  
voltage rails. They operate at 2.25-MHz fixed  
switching frequency and enter power-save mode  
operation at light load currents to maintain high  
efficiency over the entire load-current range.  
Output Current up to 600 mA  
Wide VIN Range from 2.5 V to 5.5 V for Li-Ion

Power-Save Mode at Light Load Currents  
Output Voltage Accuracy in PWM Mode ±2.5%  
Typical 15-µA Quiescent Current  
100% Duty Cycle for Lowest Dropout  
Soft Start  
The power-save mode is optimized for low  
output-voltage ripple. For low-noise applications, the  
devices can be forced into the fixed-frequency PWM  
mode by pulling the MODE terminal high. In  
shutdown mode, the current consumption is reduced  
to less than 1 µA. Switching at 2.25-MHz allows the  
use of small inductors and capacitors to achieve a  
small solution size.  
Voltage Positioning at Light Loads  
Available in a Small TSOT, and  
2-mm × 2-mm × 0,8-mm SON Package  
Operating in a forced fixed-frequency PWM mode,  
the TPS62561 devices allow simple filtering of the  
switching frequency, e.g., for noise-sensitive  
applications.

a
fixed-output-voltage version, this  
TPS62562 enables a even smaller solution size with  
no external resistors needed.  
DESCRIPTION  
The TPS6256x devices are efficient synchronous  
step-down  
dc-dc  
converters  
optimized  
for  
battery-powered applications. They provide up to  
600-mA output current from a single Li-Ion cell and  
are ideal to power mobile phones and other portable  
applications.
