Part Number: LM5141QRGEVM C1 is the input electrolytic capacitor, why put R1=1Ω in series with C1?
Isn't this equivalent to increasing the ESR of C1 and increasing the losses?
Part Number: LM5141QRGEVM Other Parts Discussed in Thread: LM5141-Q1 What is the principle of connecting R8, C19 and R7 in parallel?
Why is the sampling of the inductor current achieved by sampling the voltage across C19?
In the datasheet of LM5141…
Part Number: LM5141QRGEVM Hi Power Experts,
I have a couple of questions regarding the current sensing circuit highlighted in the below diagram,
Do we need to have the RC filter for the current sense input. What is the effect on the performance if…
Part Number: LM5141QRGEVM Other Parts Discussed in Thread: LM5150RUMEVM , Dear Support team
I need to PCB layout data to evaluate EVM(LM5141QRGEVM and LM5150RUMEVM).
I Know your pcb is designed by altium cad tool, but I don't have that s/w.
So,…
Part Number: LM5141QRGEVM Hi team,
I'd like to figure out the soft start working pattern, and I'm using the evaluation module.
-Is there any other element effect on the soft start time or behavior except the soft start capacitor Css? How?
-According…
Part Number: LM5141QRGEVM Other Parts Discussed in Thread: LM5141 , LM5145 Hello team,
I'm testing a LM5141 EVM. It is in FPWM mode and output voltage is 5V. DC input is 8V.
When I increase the CC load to over 1.6A, the output voltage goes down to…
Part Number: LM5141QRGEVM Hi team,
I was observing the voltage ringing at the switch node by using the EVM. I found the voltage overshoot and ringing is different at different input voltages. In my opinion, the ringing at VIN=12V(left figure）is much…
Part Number: LM5141QRGEVM
Test board: LM5141QRGEVM
Test condition: VOUT = 5 V, DEMB mode, Frequency = 2.2 MHz, others are default set
VIN = 12 V, IOUT = 1 A (Electronic load)
As the figure shows, I observed abnormal waveform under above test condition…
Part Number: LM5141QRGEVM Other Parts Discussed in Thread: LM5141-Q1 Hi,
I am an FAE of a distributor dealing with TI products. My customer will use LM5141-Q1. My customers will buy TI's EVM and plan to do a test before designing. The specifications…
Part Number: LM5141QRGEVM Other Parts Discussed in Thread: LM5141 Hi,
I have verified that the LM5141 device works with the TI evaluation board. The specifications are below. In my evaluation, the output voltage fluctuates at 220kHz as shown in the…
