Beschreibung

BD9137MUV is ROHM’s high efficiency step-down switching regulator designed to produce a voltage as low as 0.8V from a supply voltage of 5.5V/3.3V. 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 Switches (Nch/Nch 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
