    Hi Zhonghui / Elena, Thank you for your assistance with the above while my access to e2e was being resolved. I have partially resolved the simulation duration issues - the LMR16030 model in PSPICE does work, however it is much slower than LTSpice - 6 mins…

    Part Number: LMR16030 I've tried using this IC to design 50->12V and 50->5V regulators, but have the same unexpectedly low output from both of them. Rather than the expected voltage, around 400mV is being generated, which gradually decays to 340mV then…

    Hello, Here's what I got back from the engineer: It can operate at close to 100% duty cycle per the datasheet. The output will drop by RDS*Iout, during dropout operation. At no load, it can become problematic due to DCM ring eating into boot refresh…

    Elena, FYI. The problem I was having was caused by the output being greater than 7V and I didn't remove the pull-up resistor on the PGOOD pin.
