System Power Supply for TV Series
FET Controller Type
3ch System Power Supply ICs
BD8621EFV
No.09034EAT03
● 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:75m ? ， NchMOS: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
