FEATURES  
DESCRIPTION  
The TPS62366x is a high-frequency synchronous  
2
•
•
4A Peak Output Current  
Highest Efficiency:  
step down dc-dc converter optimized for battery-  
powered portable applications for a small solution  
size. With an input voltage range of 2.5V to 5.5V,  
common battery technologies are supported. The  
device provides up to 4A peak load current, operating  
at 2.5MHz typical switching frequency.  
–
Low RDS,on Switch and Active Rectifier  
–
Power Save Mode for Light Loads  
•
•
I2C High Speed Compatible Interface  
Programmable Output Voltage for Digital  
Voltage Scaling  
The device converts to an output voltage range of  
0.5V to 1.77V, programmable via I2C interface in  
10mV steps. Dedicated inputs allow fast voltage  
transition to address processor performance  
operating points.  
–
0.5V to 1.77V, 10mV Steps  
•
•
Excellent DC/AC Output Voltage Regulation  
–
–
–
Differential Load Sensing  
The TPS62366x supports low-voltage DSPs and  
processor cores in smart-phones and handheld  
computers including latest submicron processes. A  
dedicated hardware input pin allows simple  
transitions to performance operating points and  
retention modes of processors.  
Precise DC Output Voltage Accuracy  
DCS-Control™ Architecture for Fast and  
Precise Transient Regulation  
Multiple Robust Operation/Protection  
Features:  
–
–
Soft Start  
The devices focus on a high output voltage accuracy.  
The differential sensing and the DCS-Control™  
architecture achieve precise static and dynamic,  
transient output voltage regulation.  
Programmable Slew Rate at Voltage  
Transition  
–
–
Over Temperature Protection  
The TPS62366x device offers high efficiency step  
down conversion. The area of highest efficiency is  
extended towards low output currents to increase the  
efficiency while the processor is operating in retention  
mode, as well as towards highest output currents  
increasing the battery on-time.  
Input Under Voltage Detection / Lock Out  
•
•
Available in 16-Bump, 2mm x 2mm NanoFree™  
Package  
Low External Device Count: < 25mm2 Solution  
Size  
The robust architecture and multiple safety features  
allow perfect system integration.  
APPLICATIONS  
•
Application Processors and DSPs Power  
Supply  
The 2mm x 2mm package and the low number of  
required external components lead to a tiny solution  
size of less than 25mm2.
