Looking for µP9512Q 4-phase buck controller datasheet.
I have search and search but can't find any datasheet for the P9512Q.
Someone ?

ISL95836 Laptop PWM Controller Datasheet
The ISL95836 Pulse Width Modulation (PWM) controller IC
provides a complete solution for IMVP-7/VR12 compliant
microprocessor and graphic processor core power supplies. It
provides the control and protection for two Voltage Regulators
(VRs). The first VR, typical for Vcore, incorporates 2 integrated
drivers and can operate in 3-, 2- or 1-phase configurations. The
second VR, typical for graphics, incorporates 1 integrated
driver and can operate in 2- or 1-phase configurations. The two
VRs share...11-05-2024, 03:31 PM -
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

I have an ASUS ROG Strix- G513IH-HN008, motherboard G513-6050A3249301- MB-A04 (A4)
When I received the device, the device has no function. After an investigation, I found that the PWM CONTROLLER RT6575B (U6100) is getting warm and there is a short circuit at the 3V3 output. This normally supplies 3V3 for the embedded controller IT5571E-128 (U301). When measuring and analyzing with a thermal imaging camera, I found that some components are damaged: SLG4E42553VTR (U8500), IT5571E-128 (U301), LAN RTL8111H (U450), LOGIC 74LVC1G08GW (U1900), RT6575B (U6100) All these components are on... -
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... -
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...11-05-2024, 03:10 PM
