Description

BD9130NV is ROHM’s high efficiency step-downswitching regulator designed to provide a voltage aslow as 1V from a supply voltage of 5.5V/3.3V. It offershigh efficiency by using pulse skip control technologyand synchronous switches, and provides fast transientresponse to sudden load changes by implementingcurrent mode control.

Features

 Fast Transient Response because of Current ModePWM Control System High Efficiency for All Load Ranges because ofSynchronous Switches (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

Typical applications

  • Power Supply for LSI including DSP, Microcomputer and ASIC
