Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM5085 I am trying to simulate a buck converter using the the PSPICE .lib file in LTspice (LM5085_TRANS) and It shows an error that says "Analysis: Time step too small; time= 1.26758e-11, timestep…
Part Number: LM5085-Q1 Hi, I have designed a buck converter for my project. It works but it has much ripple on output. Noise affected other designs. I used reference design but it has not worked well. I changed the RT resistor and removed cff capacitor…
Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM5085 Hi, We are trying to use LM5085 DC-DC buck driver as buck constant current driver for LEDs. We are using Op-Amp and sense resistor to sense output current, Op-Amp output voltage is connected to…

Hello
I am using LM5085 in one of my boards: Design is for Input: 20V to 60V; Output 24V (for Vin >=24V); Output = Vin (for Vin <24V); Max power = 75W. I am seeing two issues:
1. When…
Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM5085 Hi.
I made a project with the LM5085 to reduce the voltage from 48V to 12V. The output has a minimum current of 10mA and maximum current of 2A. For the LM5085, I used WEBENCH to define the components…
Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM25085 , LM5085 These two parts seem to be identical besides the VIN spec and the odd optional but also required D2 on LM5085. If my VIN is less than 42V is LM25085 the better option?
Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM5085 Hi team,
customer use LM5085-Q1 and have problem. they set output is 12.5V, input range is from 10V to 40V.
1. if the VIN is below 13V, the output is the same with input, LM5085 work 100%duty…

Hello Team,
Could you help us to provide PMP7767 PCB CAD file? looks webside just show schematic and test report, also please confirm P-FET connected method in SW node is right?
Part Number: LM5085-Q1 Hi Team
RT pin is used to set Fsw.
IC is periodically try to sample RT pin to recognize RT resistor value to set Fsw ?
or IC samples RT resistor value ONLY one time at Power-On stage ?
