3 Description

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.
