DESCRIPTION  
External Synchronization Capable  
The TPS40210 and TPS40211 are wide input voltage  
(4.5 V to 52 V) non-synchronous boost controllers.  
They are 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. The main difference  
between the two parts is the reference voltage to  
which the error amplifier regulates the FB pin.  
Reference Voltage: 700 mV (TPS40210),  
260 mV (TPS40211)
