TPS40210QDGQRQ1

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.
