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…
Part Number: LM61440-Q1 Hello guys:
I'm a EMC engineer, Call me Mark.
I downloaded the LM61440-Q1 PSPCE model from the TI website to simulation the EMI in CST, but I found it won't perform well.
I didn't know where or what is wrong.
Here is…
Part Number: LM61440-Q1 Hi,
According to datasheet P.8, Iov (Pull down current at the SW node under over voltage condition) is 0.5mA (Typ). Could you please let us know where is pull-down? What does Iov mean? Please advise us.
Thanks and best regards…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM62440-Q1 , , LM60440-Q1 Hi,
For telematics project I need a DCDC Converter from 12V battery down to 5Vout @4A.
Vin_max 21V.
I was looking at LM60440-Q1 but I cannot tolerate EN= Vin +- 0.3V as…
Part Number: LM61440-Q1 HI,
There are two questions for Rboot.
How can the Rboot pin by pass the Cboot pin,when the boot capacitor dischare?
Why need the boot diode?Is it for reverse voltage protection?
Very appreciate for answering the question!

Hello!
I am seeing an issue with LM61440-Q1 simulation where the BIAS pin is connected directly to SW node rather than Vout. BIAS is only rated up to 16V and our input parameters are…
Part Number: LM61440-Q1 Tool/software: WEBENCH® Design Tools Hi,
i have an issue when selecting the WEBENCH Power designer for the LM61440-Q1.
if i select Vin - 20 - 31 volts and Vout 14.4 at Iout max to 4 A happy enough, however if i change just the…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Hi,
Can PGOOD be left floating when unused? Sometime an open-drain pin is specified to be pulled up even if unused.
Thanks.
