Beschreibung

The BD9141MUV is ROHM’s high efficiencystep-down switching regulator designed to produce alow voltage including 5.0V/3.3V from 2 lithium cellpower supply line. It offers high efficiency by usingpulse skip control technology and synchronousswitches, and provides fast transient response tosudden load changes by implementing current modecontrol.

Eigenschaften

  • Fast Transient Response because of Current ModePWM Control System
  • High Efficiency for All Load Ranges because ofSynchronous Rectifier (Nch/Pch FET) and SLLMTM(Simple Light Load Mode)
  • Soft-Start Function
  • Thermal Shutdown and UVLO Functions
  • Short-Circuit Protection with Time Delay Function
  • Shutdown Function

Typische Anwendungen

  • Power Supply for LSI including DSP, Microcomputer and ASIC
