Beschreibung

The LM5149 is a 80-V, ultra-low IQ synchronous buck DC/DC controller for high-current, single-output applications. The controller uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. The LM5149 can be set up in interleaved dual-phase mode with accurate current sharing for high-current applications. The device can operate with VIN as low as 3.5 V, at nearly 100% duty cycle if needed.

Eigenschaften

  • Functional Safety-Capable– Documentation available to aid functional safetysystem design
  • Two integrated EMI mitigation mechanisms– Active EMI Filter for enhanced EMIperformance at lower frequencies– Selectable dual random spread spectrum(DRSS) for enhanced EMI performance across

Typische Anwendungen

  • Industrial transport
  • Building automation
  • Test and measurement
  • Wireless infrastucture
