Led driver TPV101AD Datasheet

[crowhater]

I have tried to find the datasheet for this IC. It is a led driver ic.

on this power supply in my case. It is designed with two exactly the same IC driving one ledstripe each.

TPV 715G8620-P01-000-002S for Philips 43PUS6412

Located bottom right hand side.

Anyone with better friendship with Google than me? ;-)

Thanks in advance.

There is only a wiring diagram.

There is only a wiring diagram.

mmm...had that one. Just need to know the expected values etc on each pin.

Thanx anyway.

LED_VCC is likely 12vdc
Dim could be between 0 & 3.3~5v depending on signal from main board
EN depends on BL_ON/OFF status 0 to 3.3~5v signal from main board
Iset is likely very low around 1 volt or less, depends on led current (leds on or off)
LED is the return for the led string, likely 1~2 volts if led's are on
COMP is a reference from the +LED and is likely no more than 2.5v

What are your backlights doing? You likely have a bad led in one of the strings

Before they just flashed once and then turned of. I had a bulb in series with PSU and when I disconnected one of the backlight stripes (of two) the unit started. Then i could connect the other one and it still worked. But idf both connected then reboot. over current protection some how. BUT...when doing the procedure above and both were lit, the bulb gloved 20%. Some partial shortage....

I have fixed the problem...even if i exchanged both of these ic:s (yea...there were two identical circuits and both ic:S that had same outputs) ..one of them did not work somehow. Exchanged one of them again and now it works. The backlight turns on without any problem. But i had no datasheet for those IC:s but narrowed everything down to one of the ic:s anyway.

the voltage that you mention are there now after testing. Soo nice input here man. Thanks.
