Part Number: LM61440-Q1 I am designing in WEBENCH using the LM61440-Q1. WEBENCH is indicating PFM operation anytime the Ipp percentage goes over 50%. It seems to me that it should not go into PFM mode until Ipp percentage is greater than 200% (i.e. Ipp…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 , LM61460 Hello, - According to LM61440 datasheet, When Vout is 5V and fSW is 400KHz L1 should be 8.2uH. But in the EVK design, the inductor value was 4.7uH. Could you please elaborate on this…
Part Number: LM61440-Q1 Hi,
UVLO and PGOOD function is described on datasheet "8.3.5 PGOOD Output Operation". How about OV? Could you please let us know the timing parameter of OV (tPGDLRIT(rise), tPGDLRIT(fall)) against tPGDFLT(rise) and tPGDFLT…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Hi,
Could you please let us know how to decide CFF value? Condition is Vin=24V, Vout=3.3V. Please advise us.
Thanks and best regards, M.HATTORI.
Part Number: LM61440-Q1 Hi Team,
My customer is trying to run a Webench simulation for the LM61440-Q1: 8V-24V input, 5V output, 1.1A out, 1.1MHz fsw preferred, for a USB application. However, if they select an Iout of 3A or lower Webench returns a stability…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Hi,
According to datasheet P.27 "8.4.3.5 Dropout", we can find the following sentence.
"Instead of allowing the output voltage to drop, the LM61440 extends on-time past the end…
