now I need design the request as follow:

input: 12V-dc

output current: 10~100A /constant current  

output volotage: 2~9V

can you introduct the design or the part?

What's the difference between STORE_DEFAULT_ALL and STORE_USER_ALL, and what's the difference between "Default Store memory" and "User Store memory" in XDPP1100?

The description of the two commands in the GUI is shown below. Can you elaborate a bit more about this? Thanks!

The STORE_DEFAULT_ALL command instructs the PMBus device to copy the entire contents of the Operating Memory to the matching locations in the non-volatile Default Store memory. Any items in Operating Memory that do not have matching locations in the Default Store are ignored.

The STORE_USER_ALL command allows the user to copy the entire contents of the user section of the Operating Memory registers to the matching locations in the non-volatile multi-time programmable memory (MTP). Any items in Operating Memory that do not have matching locations in the MTP User Store are ignored.

Hi Team,

   烦请教下，这个92464无电流时，开路和对地能报么？谢谢！

OpenPower, i am unable to flash XDPE132G5D
Both dongle and chip were purchased form mouser.
I am able to flash IR35217 using same dongle with PowerCenenter so dongle is working.

Any attempt to flash the chip ends in error.
I am loosing flashing attempts.

Any help ?

Hello,

I am using the REFWLCTX15WC1 reference design with the source code given from Modus Toolbox and I am trying to limit my output transmitter power to less than 6W. I have a power receiver that requests for 10W in BPP mode, so the power transmitter is outputting 8W in BPP mode which is causing an OTP event. I know where to limit the voltage on the Vbridge in the config.xml file in the source code. But when I limit the voltage to 5.5V, the current increases to 1.5A to produce that 8W output again. Unfortunately, I don't have control of what the power receiver is requesting. So, I am attempting to limit the power transfer on the transmitter side. Any help or suggestions will be greatly appreciated. Thanks!

i have designed and developed a 24V 3A CV power supply board on ICL8810.

The design requirements are

1) input 100-300V AC

2) output 24V 3A

3) PF > 0.95

4) THD less than 10%

5) Efficiency  > 90%

6) Load and line regulation < 3%

I am sharing the schematic.

On turn ON, the voltmeter reads 24.045V - 230V input - no load

on setting load to 100mA the output is 23.96V

on 200mA its 22.93V and then right upto 1.2A its 22.9V

above 1.2A the output stops dropping.

at 1.7A its 18V

at 2.0A its 9V

I have checked everything but am not able to find the reason.

The transformer is as below

PQ2620 Ae 118

pin 3-1 primary 40T 0.35 x 2

pin 12-7 secondary 8T 0.35x4

pin 6-4 aux 5T  0.3x1

I have used the secondary output to TL431 directly, rest everything is used as per the ICL8810 Eval board guidelines.

would seek help to understand the load regulation issues and methods to diagnose and correct.

schematic is attached.

Thanks

Hello There,

We are designing a new product for automotive applications (like ECUs) that is powered by an input source of 9 to 36 V, and the ambient temperature of 65 degrees Celsius. we need a few regulators for that, which are listed below.

Regulator1: Output = 12 V 5 A; Regulator 2: Output = 5 V 10 A; Regulator 3: 5 V 15 A.  can you please list the available buck boost regulators to satisfy all our needs?

Thanks,
Sakthivel
