LM46001 - 1-A Synchronous Step-Down Voltage Converter

Description

The LM46001 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 1 A of load current from an input voltage ranging from 3.5 V to 60 V.

The LM46001 provides exceptional efficiency, output accuracy, and dropout voltage in a very small solution size.

Features

  • 1 24-µA Quiescent Current in Regulation.
  • High Efficiency at Light Load (DCM and PFM).
  • Meets EN55022/CISPR 22 EMI standards.
  • Integrated Synchronous Rectification.
  • Adjustable Switching Frequency: 200 kHz to 2.2 MHz (500 kHz default).
  • Frequency Synchronization to External Clock.
  • Internal Compensation.
  • Stable With Many Combinations of Ceramic, Polymer, Tantalum, and Aluminum Capacitors.
  • Power-Good Flag.
  • Soft St.
