Single-chip Type with Built-in FET Switching Regulator Series  
Output 1.5A or Less High-efficiency  
Step-down Switching Regulator  
with Built-in Power MOSFET  
BD9161FVM  
No.09027EAT29  
Description  
ROHM’s high efficiency step-down switching regulator BD9161FVM is a power supply designed to produce 1.2volts  
(low voltage) from 3.3volts 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)  
3) Incorporates 100% Duty function.  
4) Incorporates soft-start function.  
5) Incorporates thermal protection and ULVO functions.  
6) Incorporates short-current protection circuit with time delay function.  
7) Incorporates shutdown function Icc=0μA (Typ.)  
8) Employs small surface mount package MSOP8  
Use  
Power supply for HDD, DVS and for LSI of CPU, ASIC
