Overview

NCP1501 Dual Mode PWM/Linear Buck Converter The NCP1501 is a dual mode regulator that operates either as a PWM Buck Converter or as a Low Drop Out Linear Regulator.

If a synchronization signal is present, the NCP1501 operates as a current mode PWM converter with synchronous rectification.

The synchronization signal allows the user to control the location of the spurious frequency noise generated by a PWM converter.

Key Features

  • Synchronous Rectification for Higher Efficiency in PWM Mode.
  • Linear Mode Operation for Low Noise Output at Low Loads.
  • Integrated MOSFETs and Feedback Circuits.
  • Cycle--by--Cycle Peak Current Limit of 800 mA (typ).
  • Automatic Switching Between PWM and Linear Mode.
  • Operating Frequency Range of 500 to 1000 kHz.
  • Optimized for Ceramic Capacitors and Low Profile Inductors.
  • Thermal Limit Protection.
  • Built--in Slope Compensation for Current Mode PWM Converter.
