Part Number: LM61460-Q1 Other Parts Discussed in Thread: LM61460
Hi expert,
My customer have a question about mode transition from PWM to PFM of LM61460.
Could you please let me know the transition threshold? What parameter will the device monitor for…
Hi Elec,
The normal convention is to have the resistor in series with the CBOOT, but the LM61460 has a dedicated Rboot pin. The Rboot pin was added to the LM61460 to allow control (slowing down) of the high side FET slew rate. Slowly down the high side…

Hi Experts,
Could you please help customer's questions?
1.
The Thermal Information of LM61460-Q1 is like below.
The condition is 4 layer PCB.
Does the R value go down If it is 10 layer? Specific data. would be very helpful…
Part Number: LM61460-Q1 Hello,
I have a LM61460AAS and a LM61460AFS on two of my designs. The AAS version draws very little quiescent current under no load as expected (~60uA). However the AFS version draws approximately 7mA which is far more than I was…
Part Number: LM61460-Q1 Hi Expert,
Our customer use LM61460-Q1 to power off board load. So there might be "vout short to 14V " risk. what will happen to LM61460-Q1 if Vout is short to 14V ? Will it be broken? Thanks.
BR,
Elec Cheng
Part Number: LM61460-Q1 Hi Team,

I found an opportunity to promote TI 6A WV Buck to a automotive application and LM61460-Q1, LMQ61460-Q1, and LM63460-Q1 are three candidates for…
Part Number: LM61460 Hi team.
I manufactured a board with the attached schematic.
There is a difference in the resistance value of LM61460 "between output (TP1901/VMAIN) and GND" even though they were manufactured in the same lot. Case A) Vmain…
Part Number: LM61460-Q1 We simulated the circuit below with Pspice for TI. At first 6ms, the load current is 6A. During 6ms-8ms, the load current is about 0A. After 8ms, the load is 6A again. I am wondering why there is no waveform of SW during 6ms-8ms…
Part Number: LM61460-Q1 The measured Switching frequency is less than expected. Resistor we use for Rt is 6.2kOhm 1%. Normally we should have around 2Mhz switching for this resistance value but what we measure is 1.7Mhz. Is it a problem, what can be the…
