Part Number: LM5085 Hi TI expert
Like to know if it's possible to use a digital potentiometer in the feedback network of a LM5085 buck regulator circuit to change the output voltage and thus place the output voltage under the control of a microcontroller…
Part Number: LM5085 Other Parts Discussed in Thread: LM5141 I am looking to use the LM5085 in an application where the current limit runaway is a real concern. I have a relatively large bulk capacitor on the LM5085 output (which will look like a short…
Part Number: LM5085 Other Parts Discussed in Thread: LM5005 , Hello all,
We have a system with the following specs:
Vin typical of 48V, max of 72V
Vout of 4V going to a GSM module
Iout in idle scenario is 40 mA
Iout average when communicating 600 mA
Iout…

Hello,
I have the following schematic on TINA TI:
Pretty standard. However, looking at the transient analysis I got the following:
Using the datasheet I calculated that for a 10mOhm sense resistor I needed 12,5 Ohm on Iadj…

Part Number: LM5085 Hi,
my csutomer's schematic is as below [39-58.1V input, 5V/2A output]. , they used the lowest cost configuration according to LM5085EVM user guide. but they found the waveform of SW node is not normal, seems to be two waveforms…
Part Number: LM5085 Hi! I've done the design with two buck converters based on LM5085MY, and both of them can't achieve pre-calculated current limit.
For example one of these converters (the second one is 5.0V 2.1A with exact same layout):
…
Hi Tadeusz,
Sorry I am late, but I think I understand what is happening.
Looks like every 5ms the converter starts switching for around ~0.5ms and then stops switching for the next 4.5ms.
That's probably due to some load current from the "GSM power…
Part Number: LM5085 Other Parts Discussed in Thread: LM25085 , INA180 , LMV431 , LM321 Hi
I'm building a battery charger with the LM5085.
I want to be able to set the current limit point from a DAC.
I have based the circuit on this application note

Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM5085
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…
