TPS40211 描述
The TPS40210 and TPS40211 are wide-input voltage (4.5 V to 52 V), non-synchronous 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.
