Part Number: LMR38010 Hello expert,
As talked, there is no calculator for LMR38010 but we have WEBENCH simulation result like output ripple. Do we have a chance to have the calculator for LMR38010 which includes output ripple? Customer has output ripple…
Hi Kwon
Sorry for late reply. I tested the conducted EMI on the LMR38020EVM, The radiated EMI cannot be tested in our lab.
Changing the RT to set fsw as 400kHz/1MHz, the test is performed under same BOM except RT. Please see the attachment. Please be…
Part Number: LMR38010 I am using the LMR38010 switcher design to regulate to 12V. I am having an issue when my input voltage increases above 55V, the switcher becomes unstable and gets very hot. Below 55V and it operates fine.
All my capacitors are rated…
Part Number: LM5163 Other Parts Discussed in Thread: LMR38010
Hello,
I was wondering:
what is the behaviour of LM5163 and LMR38010 SW pin when some current is injected on Vout (from 0mA up to 50mA), with Vout=0 i.e. when Vout rail is pulled up by an external…
Hi Joshua
we will definitely choose the FPWM version of LMR38010-Q1, as we are always under 'light load' conditions (Iout<0.1A), and Vout ripple matters very much to us, and moreover, we wouldn't want the frequency to shift under light loads…
Part Number: LM5163-Q1 Other Parts Discussed in Thread: LMR38010-Q1 , Good morning
What is the maximum input leakage @150°C (or 125°C) of PGOOD port
(i.e. when voltage is regulated inside of the ‘good’ range , it should be a MOS -->…

Part Number: LMR38010-Q1 Other Parts Discussed in Thread: LMR38020
Hi ,
I found out using Webench that the LMR38010FS-Q1 is easily put into instability (Phase margin < 45°), e.g. for too small an output capacitance. What kind of response function…

1. datasheet 3page [5 Device Comparison Table] LMR38010SDDAR (FPWM=NO, SS=YES)
- If FPWM=NO, it operates as PFM. Can SS also be used?
- In the link below, it is said that SS does not operate in PFM mode.
