TECHNICAL NOTE  
System Power Supply for TV Series  
Built-in 1ch FET  
Light Load Type  
DC/DC converters  
BD8622EFV  
Description  
BD8622EFV has realized the high performance and reliability required as a power supply for thin-screen TV.  
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) High efficiency in all load area  
2) 3.0A output current  
3) PWM mode/PFM mode switch(automatic operation)  
4) Low current mode/Rorripplmord switch with terminal MODE  
5) Low RDS(ON) internal switches75m(typ.)  
6) ±1% reference voltage accuracy  
7) Programmable frequency : 250kHz-1MHz  
Can the adjustment by an external synchronization and the terminal RT resistance.)  
8) Terminal RT OPEN/SHORT detecting function  
9) Over current protection function  
10) Output over voltage/low voltage protection function (over : FB > VREF +60mV , low : FB < VREF -60mV)  
11) Timer off latch function in abnormal circumstances  
12) Thermal shutdown function  
13) Under voltage protection  
14) Soft start/start delay circuit  
15) Soft start time out function  
16) Protecting BUS function with terminal PDET  
17) HTSSOP-B20 package
