Key Specifications  
BD9A300MUV is  
a
synchronous buck switching  
Input Voltage Range  
Output Voltage Range:  
Average Output Current:  
Switching Frequency:  
High-Side MOSFET On-Resistance60mΩ(Typ)  
Low-Side MOSFET On-Resistance60mΩ(Typ)  
2.7V to 5.5V  
0.8V to VPVIN×0.7V  
3A(Max)  
regulator with built-in low on-resistance power MOSFETs.  
It is capable of providing current up to 3A.The SLLMTM  
control provides excellent efficiency characteristics in  
light-load conditions which make the product ideal for  
equipment and devices that demand minimal standby  
power consumption. The oscillating frequency is high at  
1MHz using a small value of inductance. It is a current  
mode control DC/DC converter and features high-speed  
transient response. Phase compensation can also be set  
easily.
