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.
