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.
