MARKING DIAGRAMS

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 ™ 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.

D SUFFIX

CASE 751

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.
