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 SLLMTM
(Simple Light Load Mode)
Soft-Start Function
Thermal Shutdown and UVLO Functions
Short-Circuit Protection with Time Delay Function
