Part Number: LM61440-Q1 Tool/software: Hi Team,
We would like to check LM61440-Q1 auto mode, what is the threshold for FPWM and PFM mode switching? Is there an output current limit would consider as the switching point? And will our ATE test have this…

Hi team,
About the Bootstrap capacitor, in datasheet, it is recommended to choose a capacitor of 100nF, I want to know what is the range of values of a capacitor? If I choose 10nF or 1uF, what will be the impact?
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Hi team，
When customers use 61440, the output filter capacitor capacity is larger than the input filter capacitor. When powering down, the input pin VIN will power down faster than the output…
Part Number: LM61440-Q1 Hi team，
The customer uses LM61440-Q1 to power the MCU, and the MCU has requirements for the power-on time of the LM61440-Q1. At present, the power-on time of LM61440-Q1 is about 6ms, and the MCU requires 2ms. Is there anything…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Hi team，
The customer has a few small questions about the spec of the LM61440-Q1.
1. The working voltage of the LM61440 IC is above 3V, and the initial turn-on voltage is 3.95V, right?

I am simulating TI's Buck Convertor LM61440AFS-Q1 in PSpice for TI for my project along with LISN but there is no voltage on the output of Buck convertor. Buck convertor only give 5V on the output when I add a ground on negative…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Dear expert,
Customer use LM61440 for both 2.1MHz and 400KHz case.
TI recommend 3*22uF capacitors for 400KHz which is too big form them. They want to know whether they can change them to…
