    Pioneer - AVH-z5200dab component identification

    Dear forum colleagues,

    Here I have a Pioneer - AVH-z5200dab of which the 5Vdc USB voltage is missing.
    IC451 is defective and a capacitor is defective (short circuit).

    Now I can't find a service manual for this specific unit anywhere, nor can I identify the step-down converter chip IC451.
    This is (I think) a Microchip(?) DC/DC converter in a QFN-24 package. I can't find the type on the Microchip site. It also does not work via Google and image search.
    Markings on the chip: "008 630B"

    Does anyone have an idea?

    Input of this chip is the battery voltage of the car (12 to 14 Vdc) and the output (via a Coil) is 5Vdc for the USB connection.

    Please let me know if anyone has an idea or needs more information,
    Thanks in advance!

          Thank you lotas for the very fast reply! Pinout (Vinput, ground) looks correct to me.

              Everything is correct here, it's from the service manual.

                  Good to know that the schematic comes from the service manual. Then I have enough information to carry out the repair. Thanks again, much appreciated! (I've been searching for the wrong manufacturer for days)

                      DC to DC converter? component identification
                      by MuertoGB
                      I've a SOT23-6 (i think LDO) that is glowing like a Christmas tree on the thermal camera. Pretty sure it takes 5V USB C VIN on pin 4, I'm not sure what it outputs. I've marked the pins and what they do, or what resistor they're connected to. Marking is JWE2J (Joulwatt). The component is on the main board of a Razer Kiyo Pro webcam. I think the ??? pin is EN. Thanks for any help in advance.

                      MPS NB670 NB670GQ Switch Mode Converter for Laptop Computers Datasheet
                      by Document Archive
                      The NB670 NB670GQ is a fully integrated high frequency synchronous rectified step-down switch mode converter with 3.3V fixed output voltage. It offers very compact solution to achieve 6A continuous output current and 9A peak output current over a wide input supply range with excellent load and line regulation. The NB670 operates at high efficiency over a wide output current load range. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.

                      Under voltage lockout is internally set as 4.65V. An open drain power good signal indicates the output...

                      What is this PSW1 part on a circuit board? Trying to fix a Canopus ADVC-300 DV/VHS Converter
                      by gizmo1990
                      I'm trying to fix this Canopus converter so that I can convert lots of old VHS cassettes. The problem is that it turns on for a split (and I mean split!) second, the fan jerks and then.. nothing. I've checked the power brick works. I've opened up the converter itself and been testing for shorts.



                      The image attached shows the on/off switch (which I've checked works) to the left of the yellow socket. Below the yellow socket is a green block marked 26 with a strange symbol at the front. Putting my probes either end of this block, on the silver parts, gives an open short...

                      Pioneer PL-X9 motor speed control wobble
                      by Bushcat
                      I'm starting to re-cap a Pioneer PL-X9 turntable, specifically the motor control board, because although everything tests out OK according to the service manual, the speed wavers slightly despite the quartz lock light remaining on. So, I've decided to re-cap that board since it's the cheapest next step...

                      Pioneer's passive component naming convention is clear to me. For example, CSZA R22M 35 is tantalum, radial leads, 0.22uF, 20%, 35V.

                      BUT there are two capacitors on the board which have actual Pioneer part numbers: PCL-042. I can tell they are 0.1uF, 16V but don't...

                      Hey, guys.. I was replacing an amplifier in a Pioneer AVH-210EX. When I pulled off the kapton tape, the tops of two SMD components came off with it. Can anyone help me identify these two packages?...
