Part Number: LM5008 Tool/software: Can you please say what will be the voltage across the RT resistor. Whether we have to consider the input voltage or is there any formula to calculate the voltage across the RT resistor. RT resistor value 174K and Vin…
Part Number: LM5008A Other Parts Discussed in Thread: LM5008 Hi expert,
May I clarify with you if LM5008 startup behavior would be same as LM5008A? Customer would like to make these two as 2nd source replacement.
Below the startup figure in LM5008A didn…
Part Number: LM5008 Hello guys,
One of my customers uses LM5008 for their mass-production of a product.
At this moment, they have the following questions. Could you please give me your reply?
Q. The fast recovery diode (D1, placed between SW pin and GND…
Part Number: LM5008 Datasheet: "A minimum of 25 mV to 50 mV of ripple voltage at the feedback pin (FB) is required for the LM5008."
What happened is that the design is modified. The 1 Ohm resistor in series with the output capacitor (tantalum…
Hi Colin,
I have already added another 10uF capacitor on the output, and it reduces the ripple a lot. But, the same effect appearing on the output in very less magnitude. I will check the evaluation board of LM5008 and come back to you soon.
Regards…
Part Number: LM5008 Hello, dear support team,
I need your help in using LM5008 to regulate input voltage 20V to 90V into 15V.
To have power up/down sequencing, considering that I do not want to use any transistor in this circuit, I am planning to disable…
Hi Jimmy
Based on the fact that Vout is 3.3V, I don't think the spike in the second image is that large. It should be fine. It looks to me like the dark green signal is causing that small spike, but it shouldn't affect any functionality of the circuit…
Part Number: LM5008 We want to let LM5008 to output 12V when the VIN is above 30V(not very precise). Can we use the circuit below? Will the R19 affect Ron?
Part Number: LM5008 Dear Sir
I am using LM5008MMX to convert the input range (39V -54V) into output 5V. The Schematic is given below
When testing this circuit, LM5008MMX is getting heat and steady output of 5V result is not reached. Please provide suggestion…
