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  
BD9141MUV  
No.09027EAT37  
Description  
ROHM’s high efficiency step-down switching regulator BD9141MUV is a power supply designed to produce a low voltage  
including 5.0/3.3 volts from 2 lithium cell 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 SLLM (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 : VQFN020V4040  
Applications  
Power supply for LSI including DSP, Micro computer and ASIC  
Line up matrix
