TECHNICAL NOTE  
System Power Supply for TV Series  
Built-in 1ch FET  
Synchronous Rectification Type  
DC/DC converters  
BD8621EFV  
Description  
BD8621EFV has realized the high performance and reliability required as a power supply for thin-screen TV.  
With built-in FET 1ch current mode control, the DC/DC Converter series has the advantage of high-speed load response and wide  
phase margin.  
Due to the high-speed load response, it is most suitable for TV-purpose processors with increasingly high performance, and due to the  
wide phase margin it leaves a good margin for board pattern & constant setting and so facilitates its application design.  
As a high-reliability design, it has various built-in protection circuits (overcurrent protection, output voltage abnormal protection, thermal  
protection, and off-latch function at the time of abnormality etc.), therefore as an advantage it does not easily damage in every possible  
abnormal condition such as all-pin short circuit test etc. and hence most suitable for thin-screen TV which requires the high reliability.  
Features  
1) 3A output current  
2) Low RDS(ON) internal switches (PchMOS:75mNchMOS:55m)  
3) ±1% reference voltage accuracy  
4) Programmable frequency : 250kHz-1MHz  
5) (Frequency in programmable by adjusting RT resistance or synchronizing with SYNCLK terminal.)  
6) Terminal RT OPEN/SHORT detecting function  
7) Over current protection function  
8) Output over voltage/low voltage protection function (over : FB > VREF +60mV , low : FB < VREF -60mV)  
9) Timer off latch function in abnormal circumstances  
10) Thermal shutdown function  
11) Under voltage protection  
12) Soft start/start delay circuit  
13) Soft start time out function  
14) Protecting BUS function with terminal PDET  
15) HTSSOP-B20 package
