Part Number: LMS3655 Other Parts Discussed in Thread: UCC27511 , Hello everyone,
I would like to know what is the maximum current that this converter could deliver when the input is 24 V and the output is 12 V.
According to Webench online tool, I have got…
Part Number: LMS3655 when use webbench to run simulaton,
24V to 5V , I see under 0.5A , like as 10mA , 20mA , I can see the very high efficiency performance , reach 90% above alomost.
But , when change design to 24V to 12V
I see the efficiency just…
Part Number: LMS3655 Dear all.
The input capacitor is written as ”The device is designed to be used with ceramic capacitors on the input of the buck regulator.” in the datasheet. How is this a reason? ESR? When we use different type of capacitor…
Part Number: LMS3655 For LMS3655 data sheet,
Page 8 , Iq_vin , imply that the spec for Vin= 13.5V Vout =3.3V , and Vin = 13.5V Vout=5.0V , and parameter are equal to 32 and 57 uA respectively.
Our hardware team need know the design condition , if Vin =2…

Hello,
Currently, due to difficulty in supplying ceramic capacitors,my customers are considering replacing them with electrolytic capacitors or conductive polymer capacitors.
Therefore, for the following parts, Please tell me whether…
Part Number: LMS3655 Hi,
Vref is specified as below;
On the other hand, "±1.5% Reference Voltage Tolerance" is mentioned on the 1st page of the datasheet.
Is this typo?

Part Number: LMS3655 Hi, I need a negative converter design used to function as a preregulator for an negative regulator/LDO in a power supply design. I am using a LLC converter/transformer with center-tapped secondary to step the voltage down to +/- 24V…
Part Number: LMS3655 Hi,
The characteristic of LMS3655 is specified at VIN=13.5V.
Could you show me "VIN vs Vref" for our reference?
My customer requires to keep Vref within ±1% on the actual usage(VIN=24V, Tj=80℃).
Best Regards,
Kur…
Part Number: LMS3655 Hi team,
For 24VIN, 12VOUT and 5A, Webench simulation of LM3655 currently recommends a large inductance(150uH), while 24VIN, 5VOUT and 5A is simulated with 10uH. Is it correct? Can you recommend the appropriate inductance value for…
Part Number: LMS3655-Q1
Dear Team,
we received a request if it was possible to do a frequency sweep with the external clock.
The customer has a requirement only allowing a DC/DC switching frequency lower than 300KHz. This frequency is only possible if…
