TPS40210QDGQRQ1 Description

TPS40210-Q1 and TPS40211-Q1 devices are asynchronous boost controllers with a wide input voltage (4.5V to 52V). They are suitable for topologies that require ground source N-channel FET, including boost, flyback, SEPIC, and various LED driver applications. The device functions include programmable soft start, over-current protection with automatic retry function 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 adjusts the FB pin.
