Beschreibung

The BD9141MUV is ROHM’s high efficiency step-down switching regulator designed to produce a low voltage including 5.0V/3.3V from 2 lithium cell power supply line. It offers high efficiency by using pulse skip control technology and synchronous switches, and provides fast transient response to sudden load changes by implementing current mode control.

Eigenschaften

  • Fast Transient Response because of Current Mode PWM Control System
  • High Efficiency for All Load Ranges because of Synchronous 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
