LM43600 - 0.5-A Synchronous Step-Down Voltage Converter

General Description

The LM43600 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 0.5 A of load current from an input voltage ranging from 3.5 V to 36 V (42 V transient).

Key Features

  • 1 33-µA Quiescent Current in Regulation.
  • High Efficiency at Light Load (DCM and PFM).
  • Meets EN55022/CISPR 22 EMI standards.
  • Integrated Synchronous Rectification.
  • Adjustable Frequency Range: 200 kHz to 2.2 MHz (500 kHz default).
  • Frequency Synchronization to External Clock.
  • Internal Compensation.
  • Stable with Almost Any Combination of Ceramic, Polymer, Tantalum, and Aluminum Capacitors.
  • Power-Good Flag.
  • Soft S.
