Low Voltage Buck
Regulators with External
Bias or Synchronization
Capability
The CS5141X products are 1.5 A buck regulator ICs. These devices
are fixedfrequency 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 highspeed 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 onchip 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 onchip power dissipation.
Protection circuitry includes thermal shutdown, cyclebycycle
current limiting and frequency foldback. The CS51411 and CS51413
are functionally pincompatible with the LT1375. The CS51412 and
CS51414 are functionally pincompatible with the LT1376.
