NCV51411: Buck Converter, Low Voltage, 1.5 A, 260 kHz, with Synchronization Capabilities

Description: The NCV51411 is a 1.5A buck regulator IC operating...
  • The NCV51411 is a 1.5A buck regulator IC operating at a fixed-frequency of 260 kHz. The device uses V2 control architecture to provide unmatched transient response, optimum overall regulation and simple loop compensation. The NCV51411 accommodates input voltages from 4.5V to 40V and includes an input for synchronization to an external oscillator. NCV51411 is certified for Automotive applications, and is also available in commercial grade as CS51411.
  • Features
  • V2 Architecture - Provides Ultra-Fast Transient Response, Improved Regulation and Simplified Design
  • 2.0% Error Amp Reference Voltage Tolerance - Accurate Output Voltage
  • Switch Frequency Decrease of 4:1 in Short Circuit Conditions - Reduces Short Circuit Power Dissipation
  • BOOST pin provides additional drive voltage to the onchip NPN powertransistor - Allows Bootstrapped Operations to Maximize Efficiency
