Part Number: LMZM23601EVM Other Parts Discussed in Thread: LMZM23601 Hi,
The LMZM23601 EVM went damage as i check the function. After a repeated switch on the power (vin), the modul is without function. The paramters were: Input 36V, Output 5V 1A, Last…
Part Number: LMZM23601EVM Hi team,
I have a question about the transition speed of Vout.
Why does it take as much as a second to reduce the output voltage if I dynamically change the feedback voltage divider resistance with "Vout Select"?
When the…

Hi support team,
Does the TPSM33615 have a "frequency foldback at low input voltage" function like the LMZM23601?
I want…
Hi Arpita, Thank you for your support.
I tested it with LMZM23601EVM.
LMZM23601_SW.xlsx When VIN approached VOUT, the switching waveforms of AUTO and FPWM became the same, even at a light load of IOUT = 40mA. Is it correct that the light load mode…
Yes this waveform is typical for light load operation. I've also taken a LMZM23601EVM configured for 12VIN/5VOUT at 80mA and got a similar switch node characteristic.
At higher loads the switch node will square off and adjusts to your set frequency…
Hi Onawa-san,
Sorry for the late reply. Attached is a bench scopeshot of the LMZM23601EVM under the following conditions:
VIN = 24V; VOUT = 3.3V; ILOAD = 300mA (Eload in CC mode)
In both startup cases, the 3.3V output voltage is regulated seen by…
The filter would be placed after the main inductor of the converter & before the feedback point, like so (from Understanding, Measuring, and Reducing Output Noise in ... TI E2E support forums https://e2e.ti.com › cfs-file › __key › 3362.unders... ): …
