Datasheet
2.7V to 5.5V, 2.0A 1ch
Synchronous Buck Converter with
Integrated FET
BD9130NV
General Description
BD9130NV is ROHM’s high efficiency step-down
switching regulator designed to provide a voltage as
low as 1V 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.
Features
 Fast Transient Response because of Current Mode
PWM Control System
 High Efficiency for All Load Ranges because of
Synchronous Switches (Nch/Pch FET) and SLLM^TM
(Simple Light Load Mode)
 Soft-Start Function
 Thermal Shutdown and UVLO Functions
 Short-Circuit Protection with Time Delay Function
 Shutdown Function
