Other Parts Discussed in Thread: LM3485 , DRV8832 Hi
I'm Jun, Hardware engineer in South Korea.
I designed Power supply using part LM3485.
The Control Board is composed of the motor, MCU, UART...
See the Below Block diagram
My Operating Tempeature Spec…
Other Parts Discussed in Thread: LM3485 Hello Webench team. The LM3485 is a PFET controller that can operate at 100% duty cycle. 100% duty is used in designs where Vin=Vout.
I was trying to run a design with: Vin 5-20V Vout 5V at 3Amps.
Didn't work. Changing…
Other Parts Discussed in Thread: LM3485 Hi All!
I have been using the LM3485 for over 10 years with this same circuit (different output voltage but other than that just the same), yesterday I got this new board
and nothing, the circuit just oscillate…
Hi Enzo,
I dont see or know of a competitor pin to pin for LM3489 or LM3485.
Most of the industry are using NMOS, new PMOS controllers are not really being developed.

Other Parts Discussed in Thread: LM3485 Hello All,
We are using LM3485 for one of the design.
Inductor value = 100uH & Switching frequency is 100kHz. Vin =24V & Vout = 4V @ 100mA.
Figure 3 in datasheet has propagation delay for inductors in range…
Dear Concer
I have designed an isolated supply using LM3485 Buck converter (referance from application note AN-2292). I am using MOSFET SI2309CDS-T1-GE3 & Coupled Inductor LPD5030V-333ME (make - Coilcraft). In put volatge is 24VDC & output voltage…
Other Parts Discussed in Thread: LM3485 , LM5085 Hello team,
For LM3485, to get a stable switching frequency, we have referred two different docs:

Other Parts Discussed in Thread: LM3485 Dear all.
I comfirm the LM3485 Pspice model establishing Vin : 7 ~ 18V, Vout : 10V, Iout : 4A.
LM3485 is not operating(PFET turn off) at input voltage about 9.4V
actually we will use Iout is 6A.
we want to realize t…
Hello! I have a circuit similar to Gaspar's design based on LM3485. My application is in the area of automotive circuits. PWRIN comes from a truck's battery (the value can be 12 V or 24 V). The output's value is 9 V. But there is a problem. In some…
Other Parts Discussed in Thread: LM3485 I would like to confirm ICL_ADJ of LM3485.
I think ICL_ADJ has temperature shift.
I have questions.
1. How does ICL_ADJ change by the temperature? (ex. temperature: low, ICL: low)
2. If you have, could you please …
