Hello everyone,
In ICL5102 design guide, LLC tank resonance circuit design section, when choosing the resonance capacitor, I see that when splitting the value of Cr into two capacitor, Cr1 almost equal to the calculated resonance capacitor.
should I use the calculated resonance capacitor value in Cr1 and add a small capacitor as Cr2?

Hello every one
According to the engineering guide, the output current from OTP is 100uA, and the minimum voltage should be on OTP is 780mV, my question is based on what the design guide choose 100KOhm NTC EPCOS 8507 series, when 100uA go throw this resistance, the OTP voltage should be 10 volts and this far away bigger than the maximum voltage.
My custom application operates at -40'C to 50'C.

Hello every one,
The LCC design tool provided by Infineon was great for designing the LCC topology dc-dc converter, but I can't find a reference for the design of transformer, My application takes standard AC input 220VAC, and the output should be
70-280VDC, 600-1250mA 180 Watt maximum.
Does this output voltage range supported by the LCC topology with ICL5102?
And IS there a reference to help me with resonance transformer design with this topology?, the design tool doesn't give the calculations of transformer>
Hello everyone
I need to know based on what the design guide of ICL5102 - 130 Watt based circuit determined the secondary coil turns.
For My application, the output is 180 watt, 70-280 VDC, 600-1250 mA
Is there a recommended secondary winding for this output?

Hello every one,
I'm designing led power supply, I need to know how to determine the Vbus (the voltage after PFC indcutror-diode circuit) value for 120-270 VAC input, and
180 Watt, 280 VDC max output.

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??
Hello Everyone,
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??
Hello everyone
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??
Kindly advise, could we use XDPL8221 for Max output power upto 220w for Led Driver
