3 Description
The TPS40210-EP is a wide-input voltage (4.5 to 52 V), nonsynchronous boost controller. The device is suitable for topologies which require a grounded source N-channel FET including boost, flyback, SEPIC, and various LED driver applications. The 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.
