4.5-V to 52-V wide input range current mode boost controller with 260-mV reference voltage

The TPS40210 and TPS40211 are

wide-input voltage (4.5 V to 52 V), nonsynchronous boost controllers. They are

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. The main difference between the two parts

is the reference voltage to which the error amplifier regulates the FB pin.
