The RT8205A RT8205B RT8205C dual step-down, switch-mode power supply controller generates logic-supply voltages in battery-powered systems. The RT8205A/B/C includes two pulse-width modulation (PWM) controllers fixed at 5V/3.3V or adjustable from 2V to 5.5V. An alternative LGATE1 output LG1_CP can be used for external charge pump (RT8205B). And an optional external charge pump can be monitored through SECFB (RT8205C). This device also features 2 linear regulators providing fixed 5V and 3.3V outputs. The linear regulator each provides up to 70mA output current with automatic linear-regulator bootstrapping...10-23-2024, 03:37 AM

Hi, pulled this component, (I'm assuming it's a MosFET) from an LED COB video light. Im trying to find the datasheet so I can find an equivalent replacement but no luck. Any assistance with the datasheet would be appreciated.
Failing that, a way to pick a suitable replacement component? If it's indeed a switching fet, I'm assuming I might need to measure the switching clock frequency and find a component that meets the power capacity?
Its a pair of them driving a 130w Light. Takes in 19volts. I can borrow a scope to measure the switching freq.... -
I got a dead HD6950 on Ebay to try my luck and repair it. There were a few broken off capacitors that I already replaced.
Measuring the PCI-E lanes I got somewhat weird measurements, the gpu might or might not be dead.
If I plug the GPU in, the core heats up and I also get VCore but on two inductors that measure 16 and 60 Ohms respectively (Memory and PEX I guess) there is no voltage.
On one of the two buck-controllers (APW7165) the enable pin is pulled to GND and the other controller I just cannot find a datasheet for.
So if anyone has a datasheet or at least... -
TE Circuit Protection offers the widest selection of surface-mount fuses available for addressing a broad range of overcurrent protection applications. Helping to prevent costly damage and promote a safe environment for electronic and electrical equipment, our single-use chip fuses provide performance stability to support applications with current ratings from .5A up to 20A.
TE Circuit Protection also offers the telecom FT600 fuse for telecommunications applications. This telecom fuse helps comply with North American overcurrent protection requirements, including Telcordia, GR-1089,...10-07-2024, 06:07 AM -
Hello all, I've got a defective HP Pavilion 15-cs1042ng here that won't turn on.
Unfortunately, there seems to be no boardview or schematic for this
model DA0G7EMBAE0 REV : E.
No adapter light when charger is plugged, battery not charging.
Voltage passes 1st and 2nd mosfet, nothing noteworthy on the battery charging circuit, except 1.0V on 4th pin of battery. Battery does not put out any voltage on the battery connector.
Got 19, 3.3V, and 5V rails, 3.3V on Bios chip and EC ITE8987VG,
but only 1.0V on the power button. No shorts anywhere...
