Unknown smd component
A component smd code:LX (DRL package 5pin SOT)mounts on a command card including the pin1:nc pin2:1.84v pin3:gnd pin4:1,77v pin5:3,2vcc, the pin4 is connected to the pin 66 of the MCU the pin2 is connected to a 10k resistor to a connector that communicates with another controller motor card. my question is that someone here in the community has already encountered this component, I confirm that it is not a low-power single Schmitt-trigger inverter because I have already tried it. thank you -
Some pictures...

Smd component code lfxh b550
Hi I need if someone have this reference code :lfxh b550 this is a smd ic I think an dc-dc converter.tanks -
all coils have no short,how can i check the SIO chipLeave a comment:

asus vivobook x512 problem
hi everyone
I am repairing an asus viobook x512 which has a startup problem, I noticed that the laptop receives the voltage from the charger because it has 3.3v and 5v and that the CPU has a normal heat, the bios also has the necessary voltage, but I noticed when I put 19v from power supply, before pressing power button I have a consumption of 500ma,
if anyone has a solution or a scematic I would be grateful

yes maybe, I don't have the schematics, but on the boardview it is marked R106 with a value of 20ohm, effectively now I have 25v on ACDRV, 6v on REGN. the battery charges correctly, so I mark it as problem solved, thank you very muchLeave a comment:

ps: for the bq17 that I have removed it's not a problem?Leave a comment:

I checked VCC pin (PQ24780) it is not present 0v, so I was going to check its path it comes from the power resistor PR16 which cracked(i dont now how
, after change it I have now all the voltage on the IC charger

yes tanks mcplslg123
REGN is 0v,the ic charger still good its working on another board and soldered correctly
resistance to ground of the REGN pin is 50kLeave a comment:

hi mon2 sorry yesterday I couldn't finish the work we started, indeed you were right the transistor PQ17 receives a voltage of 9v on its gate and this short circuit with the ground and ACDET, so I removed the transistor and there I have 2.6v on ACDET, but still ACDRV low (18.75v) and ACOK 0v...Leave a comment:

ACDET: 124k resistance to groundLeave a comment:

voltage on pr31 is 19.27v coming from adapter, the other side is 0v
I can confirm that all connections are correct and checked....Leave a comment:

this schematic is for the same board?...Leave a comment:

tanks mon2, and I hope everything is going well for you
so the voltages I gave are without battery, and I changed the charger ic with another one that works on another board, same result...Leave a comment:
