1.5 A, 260 kHz and

Regulators with External

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 V2
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.
