DESCRIPTION

External Synchronization Capable

The TPS40210 and TPS40211 are wide input voltage

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

They are 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. The main difference

between the two parts is the reference voltage to

which the error amplifier regulates the FB pin.

Reference Voltage: 700 mV (TPS40210),

260 mV (TPS40211)
