1.5 A, 260 kHz and

520 kHz, Low Voltage Buck

Regulators with External

Bias or Synchronization

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.

Features

• V2 Architecture Provides Ultra–Fast Transient Response, Improved

Regulation and Simplified Design

• 2.0% Error Amp Reference Voltage Tolerance

• Switch Frequency Decrease of 4:1 in Short Circuit Conditions

Reduces Short Circuit Power Dissipation

• BOOST Lead Allows “Bootstrapped” Operation to Maximize

Efficiency

• Sync Function for Parallel Supply Operation or Noise Minimization

• Shutdown Lead Provides Power–Down Option

• 85 µA Quiescent Current During Power–Down

• Thermal Shutdown

• Soft Start

• Pin–Compatible with LT1375 and LT1376
