Part Number: LMR14030-Q1 Hi, team.
The frequency setting range of the LMR14030-Q1 is specified as 2.5 MHz as the maximum.
But does it need to be within 2.5 MHz considering the deviation of the set frequency and the shift due to the frequency spread…
Part Number: LMR14030 Hi, team.
Is an outflow electric current from a EN terminal included in a specification of ISHDN?
If yes, isn't there leakage current of anything but a EN terminal?

Part Number: LMR14030-Q1 Hi
I have a question about this device. This device has a spread spectrum (SS) option device.
However if the external spread spectrum clock is input to SYNC pin at NOT SS option device, the switching can be traced the spread…
Hi Dongbao,
When test Rjc, only case top is thermal conduction path, all other surfaces is thermal insulated, LMR14030 only has thermal pad on case bottom, so the Rjc is higher than Rja. Rjc is more applicable for package with metal heat-sinking on…
Hi Jason-san,
Thank you for your answer.
I have an additional question.
Is LDO mode applied LMR14030-Q1?
I'm understanding that it is not applied because LMR14030 has the low side FET to recharge BOOT capacitor.

Part Number: LMR14030-Q1 Hi
Our customer will set the 55ms for SS time. However if there are considerd with some variations of the use condition the SS time will be increased to 160ms(max). Is there any concerns?
Or is there any limitation of SS time…
Part Number: LMR14030-Q1 Hi,
We got a question from the customer about LMR14030-Q1. Could you help us?
[Question] They are considering using two LMR14030-Q1. But they need compact layout. Therefore they are considering 2 type of EN resistors circuit…
Part Number: LMR14030-Q1 Hi, team.
The deviation of the frequency of LMR14030-Q1 is prescribed with +/-8% at 2MHz, but how much is the deviation in case of 500kHz?
Even if a frequency changes, is it same?
Best Regards,
Andy-san,
Please neglect above question.
I have an another question.
You said "but inductor current is near zero because of negative (Vin-Vout)".
Is this supposed light load?
I think that inductor current is not zero if the load is heavy.
