BD8601FV
No.09034EAT01
●Description
BD8601FV 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.
