Beschreibung
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.
Eigenschaften
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
Typische Anwendungen
- Power Supply for LSI including DSP, Microcomputer and ASIC
