DESCRIPTION  
Internal 250 mN-Channel MOSFET Switch  
The TPS40222 is a fixed-frequency, current-mode,  
non-synchronous buck converter optimized for  
applications powered by a 5-V distributed source.  
With internally determined operating frequency,  
soft-start time, and control loop compensation, the  
TPS40222 provides many features with a minimum of  
external components.

Internal Soft-Start  
Internal Loop Compensation  
Short Circuit Protection  
Thermal Shutdown  
The TPS40222 operates at 1.25 MHz and supports  
up to 1.6-A output loads. The output voltage can be  
programmed to as low as 0.8 V. The TPS40222  
utilizes pulse-by-pulse current limit as well as  
frequency foldback to protect the converter during a  
catastrophic short circuited output condition.  
High Efficiency Up to 92%
