Hello every one
My question is, will ICL5102 based power supply circuit, will support 180 Watt, 280 VDC output??
If so, is there any design tool configurator to use??
I'm working on 180Watt AC-DC led power supply with 600-1200mA and 120-277V output, and I'm working on XDPL8221 design.
My question is, Does XDPL8221 support this power and voltage output range??
If so, Is there a design tool to configure the parameters??
I'm using XDPL8221 Led driver for my led power supply application with input voltage 120-270 VAC and output specs of: 180 watt, 75-270 VDC, 600-1200 mA
First of all I'm not sure if it will meet this output requirements, but I'm working on the design parameters in design guide.
My question is Will I need desktop GUI for software configurations, if so where I can find it???
Another question is If the xdpl8221 is not suitable for the voltage, power range, is there alternative that support dimming?
Is there any design configurations tool that can help me with the design parameters??
I'm working on Led power supply take input 120-270 VAC, and output 120-277VDC, 600mA-1200mA and 180 Watt.
I'm using XDPL8221 in my hardware desing, but I'm not sure that it can be used for this power range, Am I right?
Is there any tool to help with design parameters??
I'm trying to fix some problems on our new power supply designed with ICL5102.
This power supply seems to work almost properly: good full load regolation, no noise, good startup...
But when I measure the gates signals of the HB, I found there is not a duty cycle of 50% (with associates dead time).
On the picture below:
green = gate HS
blu = gate LS
Yellow = LSCS
Is there a way to change the duty cycle of the HB?
Or maybe do I have any kind of protection that modify the duty cycle?
Thanks a lot in advance,

i am facing issue to install .dp vision on my computer.
pop-up message ask to download java runtime environment 1.7 .
I have install .dp vision on another system around last week but such issue not occurred or never ask for java runtime environment 1.7
i have install same several time but issue occured first time only.
currently I am taking TLD7002-16ES # TLD7002-16ES driver in operation. The driver is mounted on our own PCB. NeitherOTP programmer board or the OTP wizard is used. The driver always returns 0x01 as output status ("internal fault" always on) and the driver stays in init mode (regarding ACK byte). The same effect comes while operating with Arduino.
Some relevant infomation read from register:
OST Status: 0x00 for all channel
OTP Status: 0x00
Otp register value read, starting from 0x83:
I am considering providing backup power to the Vcc pin of the ILD8150XUMA1. Under normal circumstances, we plan to supply approximately 60V to the Vin pin. However, there are potential fault conditions where the voltage may drop to as low as 1V. In such situations, we want the internal logic of the chip to continue functioning normally. My question is: Will supplying a backup voltage of around 6.8V to the Vcc pin in the absence of Vin cause any issues or complications?
I understand VCC provides the output voltage from internal regulator but still can this be use to provide 6.8V externally.
