are fixed ? frequency operating at 260 kHz and 520 kHz. The regulators
use the V 2 ? control architecture to provide unmatched transient
response, the best overall regulation and the simplest loop
compensation for today ’s high ? speed logic. These products
accommodate input voltages from 4.5 V to 40 V.

The CS51411 and CS51413 contain synchronization circuitry. The
CS51412 and CS51414 have the option of powering the controller
from an external 3.3 V to 6.0 V supply in order to improve efficiency,
especially in high input voltage, light load conditions.
The on ? chip NPN transistor is capable of providing a minimum of
1.5 A of output current, and is biased by an external “boost” capacitor
to ensure saturation, thus minimizing on ? chip power dissipation.
Protection circuitry includes thermal shutdown, cycle ? by ? cycle
current limiting and frequency foldback. The CS51411 and CS51413
