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  
BD9151MUV  
No.09027EAT11  
Description  
ROHM’s high efficiency dual step-down switching regulator BD9151MUV is a power supply designed to produce a low  
voltage including 1.8 volts or 1.2 volts from 2.8 volts to 5.0 volts power supply line. Reset circuits of input power supply  
voltage and external Pch MOSFET gate controller are incorporated. 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) Incorporates soft-start function.  
4) Incorporates Thermal / ULVO protection functions.  
5) Incorporates thermal protection and short-current protection circuit with timer latch function. .  
6) Incorporates shutdown function Icc=0µA(Typ.)  
7) Incorporates reset function  
8) Incorporates Pch MOSFET gate controller  
9) Employs small surface mount package : VQFN020V4040
