DESCRIPTION  
8-Pin, 3-mm x 3-mm SON with Ground  
Connection to Thermal Pad  
The TPS40040 and TPS40041 dc-to-dc controllers  
are designed to operate from a 2.25-V to 5.5-V input  
source. To reduce the number of external  
components, several operating parameters are fixed  
internally; namely, frequency, soft start time, and  
short circuit protection (SCP) levels. For example, the  
operating frequencies of TPS40040/1 are 300  
kHz/600 kHz, respectively.
