The TPS40210 and TPS40211 are wide-input voltage (4.5 V to 52 V), nonsynchronous boost
controllers. They are suitable for topologies which require a grounded source N-channel FET
including boost, flyback, SEPIC and various LED Driver applications. The 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.
