Overview

NCP1547 1.5 A, 340 kHz, Buck Regulator with Synchronization Capability The NCP1547 is a 1.5 A buck regulator IC operating at a fixed−frequency of 340 kHz.

The device uses the V2™ control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high−speed logic.

The NCP1547 accommodates input voltages from 4.0 V to 40 V and contains synchronization circuitry.

Key Features

  • V2 Architecture Provides Ultra.
  • Fast Transient Response, Improved Regulation and Simplified Design.
  • Wide Operating Range: 4 V to 40 V.
  • 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.
