Power Management ICs Forum Discussions

Dear Infineon engineer，

I want to use TLE7386-3E chip to generate 5V, 3.3V, and 1.3V voltages. However, in my design, it's not for MCU. Therefore, for the pins related to reset, RO_1, RO_2, and the pins related to watchdog, WDI, WDO, can I just give them a constant high or low voltage level? That is, I don't need these monitoring functions, as long as the chip can generate voltages normally.

Your help with this matter is invaluable to me, and I thank you in advance.

I need to design 2 isolated supplies. For both, I am fed by a PFC front-end with a input voltage range 350V ~ 410V. My output shall be 28V. The 1st supply should deliver 200W and the 2nd supply should deliver 400W. I was first considering the LLC topology with ICE2HS01G-DS but after going into some reference material, found that EMI will be a problem later on due to the varying frequency of the converter. I therefore am considering a forward converter topology with an active clamp. I want to use the same topology for both designs in order to re-use circuitry and minimize risk. I came across the XDPP1100 digital power controller but what I would like to verify is whether the choice of topology and controller is in fact the optimum choice. I am not space constraint but my operating temperature will be at a maximum of 65 deg C, so efficiency is critical. I do not have forced air to cool down my design so I will have to rely on conduction cooling. Some inputs or advice will be greatly appreciated.

Hello,

I was looking to see what the differences in firmware for both IC chips WLC1115 and WLC1150. When I attempt to create a new applications project on Modus Toolbox I only get the peripherals option with the WLC1115 but not the WLC1150. Do both chips use the same firmware?

Thanks
