Part Number: LM5008A Tool/software: Hi expert,
Customer would like to have 200ms delay time on 3.3Vo after Vin reach a target threshold e.g. 54Vin.
The only way we can think of is using RT/SD pin, maybe have a R divider and/or a RC delay but RT pullup…
Part Number: LM5008A Tool/software: Can you please say what will be the voltage across the RCL pin resistor. How to calculate the voltage across the RCL resistor. Rcl resistor voltage is 665K.
Part Number: LM5008A Tool/software: In the part number
LM5008AMM/NOPB
Can you please say what will be the Voltage for the capacitor that connected between BSW pin and Sw pin Or please tell us how to calculate or find the voltage for the that capacitor…
Hi EricLee
Today, I tested again.
Finally I found the solution.
I changed to change R3 value 0.82ohm to 3ohm. but the problem is still existed.
Actually, I added more Capacitor at voltage output node(4.7uF 1ea, 10uF 1ea) besides 22uF(Cout) ,
because ouput…
Part Number: LM5008A Tool/software: Hi expert,
Customer used LM5008A and measured OCP waveform with e-load. CH1 is 3.3Vout, and CH2 is inductor current.
The first trip point the inductor current is about 0.58A which seems reasonable. Could you please…
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: LM5008A Hello I am using the unencrypted model of LMR5008 buck converter on LTSPICE XVII. When i run the simulation, i encounter the same problem where it states "u1:v8: requires a minimum of 5 parameters. Only 3 specified."
Can…
Part Number: LM5008A Other Parts Discussed in Thread: LM5008 , Hello all,
After importing the Model of LM5008A "LM5008_TRANS.LIB", see the header below, I get an error with V8.
This seems to be a Pulse-Voltage source:
V8 U6 0 PULSE 0 1 100N
LTSpice…
Part Number: LM5008A Dear Team
The customer use equation (1) to calculate the switching frequency.
But different from the value of capture's waveform. Could you help explain the different frequency?
The spec is : Vin=54V,Vo=3.3V、Io=122mA、L=330uH…
