Single-chip Type with Built-in FET type Switching Regulators  
Flexible Step-down  
Switching Regulator  
with Built-in Power MOSFET  
No.10027EAT45  
BD8649EFV  
Description  
The BD8649EFV is a synchronous step-down switching regulator that integrates 2 low resistances N-channel MOSFETs.  
It achieves 3A continuous output current over a wide input supply range.  
Current mode operation provides fast transient response and easy phase compensation.  
Feature  
1) Synchronous rectification with built-in FET type DC/DC converter  
2) 3.0A output current  
3) Range of operation power-supply voltage 4.5V18V  
4) Reference voltage FB 0.8V±1%  
5) Programmable frequency 100kHz600kHz  
6) Over current protection function  
7) Thermal shutdown function  
8) Under voltage protection  
9) Soft start time out function / Soft start delay circuit  
10) Programmable OFFLATCH time  
Applications  
FPD,DVD,HDD Recorder,STB,Amusement,Other
