3 Description
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.
