DESCRIPTION
The TPS40210 is a wide input voltage (5.5 V to 52 V)
non-synchronous boost controller. It is 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.
