    Power-One solar Inverter driving me NUTS!!!
    by mitsu2k
    Hello folks, this is a last ditch effort. I thought I would seek your expertise before giving up.. I have been working on this thing for over 2 months and have gotten nowhere. Here is the issue:
    Inverter powers on and immediately red GFI light comes on and inverter will not complete the initialization process.
    There is no error code on the screen. I have removed most of the Y capacitors and tested to no avail.
    All relays are good.
    I replaced the current transducer- same problem. Checked most of the transistors and diodes and all appear good. I wish I could get my hands...

    ISL6556ACB ISL6556ACBZ ISL6556ACR ISL6556ACRZ PWM Controller Datasheet

    Optimized Multi-Phase PWM Controller
    with 6-Bit DAC for VR10.X Application
    The ISL6556A controls microprocessor core voltage
    regulation by driving up to 4 synchronous-rectified buck
    channels in parallel. Multi-phase buck converter architecture
    uses interleaved timing to multiply channel ripple frequency
    and reduce input and output ripple currents. Lower ripple
    results in fewer components, lower component cost, reduced
    power dissipation, and smaller implementation...

    trying to recover data from the Toshiba / KIOXIA SSD on the XPS 13 2-in-1
    by francisew
    Continuing my saga of trying to recover data from the Toshiba / KIOXIA SSD on the XPS 13 2-in-1. It is actually a single-chip NVMe storage device, including the memory and controller in a single package (not an eMMC as I wrote above). The drive appears to come in two formats. One is the single-chip direct to board version included on the Dell XPS13 7390 2-in-1. The other format is an m.2 22x30 NVMe carrier board that also includes a handful of external power regulation components.

    It's unfortunate that I haven't been able to find datasheets for the Toshiba/KIOXIA BG4 series NVMe chips...

    Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages

    The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

    Securing a good thermal interface between...

    Acer predator XB241YU Component identification
    by Shulgin
    Hello everyone,
    I have a problem with my Acer predator XB241YU screen. When I plug it in, the startup LED turns on instantly, and I can't turn off the screen without unplugging it.
    After disassembly and inspection of the electronic cards I found what looks like a broken inductor, it is marked with the letter A and is at location L58.
    In the first photo you can see the broken component, in the second photo you can see where it is on the board, in the third photo you can see the silkscreen and in the fourth photo you can see the identification sticker of the main board
    I...
