TECHNICAL NOTE

System Power Supply for TV Series

Built-in 1ch FET

Synchronous Rectification Type

DC/DC converters

BD8628EFV, BD8624EFV

●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) 1ch 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
