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…
Hello,
The TPS62810M, TPS628304, TPS62827A or TPS62A04AB would match these requirements.
Do you have more specific requirements, such as fast load transient response, light load efficiency, adjustable switching frequency, I2C control, etc.? Then I…
Hello Kyohei,
thanks for reaching out in E2E.
Figure 9-29 and 9-30 in the datasheet are showing the output voltage ripple. The setup is as described at the beginning of section 9.2.3. Please note that the oscilloscope bandwidth was set to 20MHz in…
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... ): …
