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  
BD9150MUV  
No.10027ECT13  
Description  
ROHM’s high efficiency dual step-down switching regulator BD9150MUV is a 2ch output power supply designed to produce  
a low voltage including 3.3,1.2 volts from 5.0 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 (Pch/Nch FET)  
and SLLMTM (Simple Light Load Mode)  
3) 2ch output power supply.  
4) Each of EN controls 2ch output.  
5) Incorporates soft-start function.  
6) Incorporates ULVO functions.  
7) Incorporates thermal protection and short-current protection circuit with time delay function.  
8) Incorporates shutdown function Icc=0μA(Typ.)  
9) Output current max 1.5A/1.5A.  
10) Employs small surface mount package : VQFN020V4040
