System Power Supply for TV Series

FET Controller Type

3ch System Power Supply ICs

BD8628EFV, BD8624EFV

No.09034EAT06

●Description

BD8628EFV / BD8624EFV have 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) 11ch synchronous rectification step-down system DC/DC converter

2) Soft start, soft off function

3) Built-in low voltage / overvoltage protection function

4) Built-in overcurrent protection function

5) Frequency setting by external resistance is available. (RT terminal)

6) Protection time setting by external resistance is available. (RSET terminal)

7) Built-in RT / RSET terminal open/short protection function

8) Protection control with built-in sequencer

9) Built-in adjustment function time of off latch

10) Built-in error state detection signal output function

11) Built-in tracking function

12) Corresponded to protecting bus

13) Load current Maximum 3A

14) HTSSOP-B24 Package
