The TPS40210-Q1 and TPS40211-Q1 devices 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.
