Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 , Hi team,
I plan to use LM25149 in dual phase operation and control the PFM and FPWM from external MCU GPIO.
Is it possible to pull up secondary LM25149-Q1 to VDDA of the primary LM25149…

Hello,
There is a PSpice transient model on the website for LM25149-Q1 , but unfortunately, it is encrypted, so I can't import it into Tina. How can I…
Part Number: LM25149-Q1 Hi team,
How long is the EN to VDDA start up delay?
I measured it and it varies 0.1ms to 2ms.
Is it the expected value?
regards,
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 , LM25148 We're hoping to use the LM25149-Q1 in our infotainment platform to provide a pre-regulated 5V supply to feed our other regulators.
The feed to the LM25149-Q1 would be via an…
Part Number: LM25149-Q1 Hi teams,
I hope you’re doing well!
Can you help explain how the following parameters are calculated?
For example, how do we get Fc=60KHz and Cout=100uF in the calculation formula of Rcomp?
Is Cbw=31pF a fixed value? If…
Part Number: LM25149-Q1 Hi team,
VDDA supply is regulated to 3.3V when in PFM mode with light load or no load on the output as below in the datasheet. .
An internal 5-V linear regulator generates the VDDA bias supply. Bypass VDDA with a 100-nF ceramic…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 , LM5149-Q1EVM-400 , PMP20804 LM25149-Q1 Is this part support for 40A load?
My input is 24VDC and Output is 12V/40A is this the right part to use.
if not suitable then suggest the part which…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Hi team,
I have promoted our LM25149-Q1 to automotive customer used in digital cockpit.
Besides LM25149(supply for main soc, 3.3V/20A), they still have many other WVB converter for primary…
Part Number: LM25149-Q1 Hi team,
I would like to control PFM/FPWM mode depends on the system operation mode.
I pull up PFM/SYNC pin to VDDA through 22kohm register for PFM operation,
and pull down to GND through transistor.
I concern pull VDDA to GND…
