Single-chip Type with built-in FET Switching Regulator Series  
Output 2A or More High-efficiency  
Step-down Switching Regulator  
with Built-in Power MOSFET  
BD9130NV  
No.09027EAT36  
●Description  
ROHM’s high efficiency step-down switching regulator BD9130NV is a power supply designed to produce a low voltage  
including 1 volts from 5.5/3.3 volts power supply line. Offers high efficiency with our original pulse skip control technology  
and synchronous rectifier. Employs a current mode control system to provide faster transient response to sudden change  
in load.  
●Features  
1) Offers fast transient response with current mode PWM control system.  
2) Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET)  
and SLLMTM(Simple Light Load Mode)  
3) Incorporates soft-start function.  
4) Incorporates thermal protection and ULVO functions.  
5) Incorporates short-current protection circuit with time delay function.  
6) Incorporates shutdown function  
7) Employs small surface mount package : SON008V5060  
●Use  
Power supply for LSI including DSP, Micro computer and ASIC
