FEATURES  
DESCRIPTION  
The TPS6236x are  
a family of high-frequency  
2
•
3A Peak Output Current  
Highest Efficiency:  
synchronous 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 3A 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 devices convert to an output voltage range of  
0.77V to 1.4V (TPS62360/62) and 0.5V to 1.77V  
(TPS62361B), programmable via I2C interface in  
10mV steps. Dedicated inputs allow fast voltage  
transition to address processor performance  
operating points.

TPS62360/62: 0.77V to 1.4V, 10mV Steps  
TPS62361B: 0.5V to 1.77V, 10mV Steps  
•
•
Excellent DC/AC Output Voltage Regulation  
–
–
–
Differential Load Sensing  
The TPS6236x supports low-voltage DSPs and  
processor cores in smart-phones and handheld  
computers including latest submicron processes.  
Dedicated hardware input pins allow 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 TPS6236x devices offer 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 and Lockout
