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  
No.10027ECT04  
BD8312HFN  
Description  
BD8312HFN produces step-down output including 1.2, 1.8, 3.3, or 5 V from 4 batteries, batteries such as Li2cell or Li3cell, etc.  
or a 5V/12V fixed power supply line.  
This IC allows easy production of small power supply by a wide range of external constants, and is equipped with an external  
coil/capacitor downsized by high frequency operation of 1.5 MHz, built-in synchronous rectification SW capable of  
withstanding 15 V, and flexible phase compensation system on board.  
Features  
1) Incorporates Pch/Nch synchronous rectification SW capable of withstanding 1.0 A/15V.  
2) Incorporates phase compensation device between input and output of Error AMP.  
3) Small coils and capacitors to be used by high frequency operation of 1.5MHz  
4) Input voltage 3.5 V – 14 V  
Output current 1.2A(7.4V input, 3.3V output)  
0.8A(4.5V input, 3.3V output)  
5) Incorporates soft-start function.  
6) Incorporates timer latch system short protecting function.  
7) As small as 2.9mm×3 mm, SON 8-pin package  
HSON8  
Application  
For portable equipment like DSC/DVC powered by 4 dry batteries or Li2cell and Li3cell, or general consumer-equipment  
with 5 V/12 V lines
