Request for identification of the system as in the photo ICM 801, inscription S7150 A839. It acts as a driver for the MMIS60R580P transistor of the inverter in the Samsung UE 32N4002K TV.

Probably the TPS7150QD chip 500mA, Low-Dropout Voltage Regulator. Compare the application with what is on the disc.

Buddy dudi2003, have you solved the problem with this integrated circuit? I have the same case and can't pinpoint what kind of system it is.

Same case for me without finding the solution, pending repair for several months.

There may be a problem with that. For example, the Russians give OB2269, from what I understood on the wires, because the pins probably do not match 1: 1, but they wrote that it works.

Impossible, it's a PWM driver. Did someone put OB2269 for this one and the power supply worked?

Hello, in the S7150 circuit, the transistor is CM801 blue, someone removed it for me, what is the capacity? Does anyone know where to get the S7150 apart from Ali

You can buy it at ASWO for only PLN 87.

Hello, I wrote a week ago about identifying the CM801 element (how much Pf) I have OB2269 and I'll see if it works, The topic is watched by 8 people and no one knows what kind of kondzio it is?

Witan,TPS7150QDR TPS7150QD TPS7150 7150Q SOP8 available on aliex PLN 18.50

Not any TPS, just the chip is called SEM7150A. And the CM801 capacitor is 220pf / 1kV (ceramic, blue).

And the CM801 capacitor is 220pf / 1kV (ceramic, blue).

I don't have this TV anymore, it has been playing at the client's for 2 weeks.
I did it on a board like in the attachment on the wires.
