TECHNICAL NOTE  
Single-chip built-in FET type Switching Regulator Series  
High Efficiency  
Step-down Switching Regulator  
BD9137MUV  
Description  
ROHM’s high efficiency step-down switching regulator BD9137MUV is a power supply designed to produce a low voltage  
including 0.8 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/Nch 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 Icc=0μA(Typ.)  
7) Employs small surface mount package : VQFN020V4040
