DESCRIPTION

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.
