PI-Expert (offline version) crashes when loading a design created with the web-based version...

Forums: AC-DC Conversion Forum

I just realized that the cloud version of PI-Expert has many improvements and features that are not available for the offline version. New magnetics generator, PCB tools export, change the # of output caps, to name a few. However, when trying to load a design created by the cloud version

I'm looking for the UL1577 and TUV (EN60950 and EN62368) safety approvals for product certification. Where to find it?

LYT5216D-TL shorting (damage) issue 24V 150mA design

Forums: LED Drivers Forum

Hi, I have used LYT5216D-TL for 24V, 150mA LED driver non-isolated design. I got reference schematic for this requirement from PI's support team and built a proto types around this. During testing I am facing issue like LED driver board blown out randomly and in all cases we can see

Heatsinking INN3675C across the isolation barrier

Forums: AC-DC Conversion Forum

Hi, We wish to mount INN3675C (inSOP-24D) across the isolation barrier as ever. Its a 20W, 90-265VAC flyback...but its in CCM at 105VAC, so we need to heatsink it well. We have it on a daughter board, which is resting on two kind of PCB "pieces" which have castellated pads

Heatsink area - Output Rectifier Stage - 50.34 W total loss

Forums: AC-DC Conversion Forum

The calculated values for heatsink area for the output rectifier were as it follows: 1371175 mm^2 (when custom aluminum is selected) 355446015 mm^2 (when double-sided 2-Oz PCB is selected) What that means? Do these numbers make sense? The SR used on main output is: IRL540NPBF. Total losses = 50.34 W

Maximum Allowed Current - INN3670C-H606

Forums: AC-DC Conversion Forum

Hello, As far as I know, the INN3670C-H606 is capable of 100W output. I'm trying to achieve a single-output 5V/20A, but the PI-Expert software won't allow me to go beyond 15A. I have attached the design file! Thanks

Difference between Innoswitch CE, CP and EP?

Forums: AC-DC Conversion Forum

Hi, Is the only difference between Innoswitch CE, CP and EP just the VDS, the Current limit , the RDSon and the bias current?

Reference design, application note, or go PI-Expert for this design?

Forums: AC-DC Conversion Forum

Hello, I prefer to start with a reference design for any new power design, hence the name "reference". I'm trying to make a compact 100W Flyback for powering RGB LED strip. It is a universal input (90~265 VAC) with a single output (5V/20A) isolated. I was wondering if there's any
