DESCRIPTION  
The TPS40210 is a wide input voltage (5.5 V to 52 V)  
non-synchronous boost controller. It is suitable for  
topologies that require a grounded source N-channel  
FET, including boost, flyback, SEPIC, and various  
LED driver applications. Device features include  
programmable soft start, overcurrent protection with  
automatic retry, and programmable oscillator  
frequency. Current-mode control provides improved  
transient response and simplified loop compensation.  
Low-Current Disable Function  
APPLICATIONS  
Down-Hole Drilling  
High Temperature Environments
