Part Number: LMS3655-Q1 Dear Sir,
My customer would use LMS3655-Q1 to design a infotainment(10V~36Vin, Vo=4.2V/5A).
have a key spec: light load eff >80%during Vin=36V Io=4.2V/8mA
He have a confuse: he saw datasheet fig24 eff. curve basic can meet his…
Part Number: LMS3655 Hi team,
I have two questions about LMS3655.
(1) Input voltage is up to 40V. Why the output voltage is only up to 20V? Is it caused by control method?
(2) In datasheet, it says that "Operation below 3.3 V and above 6 V may require…
Part Number: LMS3655 Hi,
A value of the FB resistances of Figure 23 is wrong. This is a value of 3.3V.
The ESR of the output capacitor is 25mohm, but the input of more than 10mohm suffers an error in WEBENCH.
Regards, PAN-M
Part Number: LMS3655 Dear all,
Our customer designed LMS3655 by WEBENCH. However, the output oscillated. The conditions are as follows; Input: 16.5 - 19 V Output: 5 V Iout : 4 A
Cff of this output is 1.2nF. They delete this Cff, or less than 100pF, the oscillation…
Part Number: LMS3655 Dear Sir/Ms.
Excuse me, my client is looking for a 4.2V~40Vmax output 5A and has an ISO16750 specification for Buck. I read the LMS3655 datasheet and did not write the ISO16750 specification. I would like to ask if this one has it…
Hello,
You can refer to the device datasheet for the pre-regulator and PMIC which will provide all of the details on these parts.

Part Number: LMS3655 Hi, team.
Can the LMS3655 operate with BIAS=GND?
It is described as connecting BIAS to GND or other power supply at 15V or more.
(4) Operation above 15 V requires the BIAS pin grounded or powered by an external source. A maximum of…
Part Number: LMS3655-Q1 Tool/software: WEBENCH® Design Tools When simulating LMS3655AQRNLRQ1 in WEBENCH with Vout=5.05, 4.5A then the minimum allowed Vin is 6.7V. According to the datasheet it should be around 5.5V.
Why is the VinMin so high in WEBENCH…
Part Number: LMS3655-Q1 Hi team,
Does LMS3655-Q1 have a low-voltage output mode?
I have one question at using Vin < Vo .
If Vin=5V, Vo= 5.5V
When the input is reduced to 5 volts, can the output be set to 5.5 volts and output? If 5V is input, what…
Part Number: LMS3655 Other Parts Discussed in Thread: UCC27511 , Hello everyone,
I am using the LMS3655AMRNLT synchronous Buck converter to step down 24 V to 12 V. The schematic and PCB design are almost done. The last one was made following the indicated…
