Capability
The CS5141X products are 1.5 A buck regulator ICs. These devices
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
are functionally pin−compatible with the LT1375. The CS51412 and
CS51414 are functionally pin−compatible with the LT1376.
