• External Synchronization Capable

• Reference700-mV (TPS40210), 260-mV

(TPS40211)

The TPS40210 and TPS40211 are wide-input voltage

• Low Current Disable Function

(4.5 V to 52 V), non-synchronous boost controllers.

They are suitable for topologies which require a

grounded source N-channel FET including boost,

• LED Lighting

flyback, SEPIC and various LED Driver applications.

• Industrial Control Systems

The device features include programmable soft start,

overcurrent

protection

with

automatic

retry

and

• Battery Powered Systems

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.
