Hi Sam,
Sorry, I think I did not explain clearly.
I have bought the LM73606EVM-5V-400K and tested it. I want to reference internal design.
May you share the design files of LM73606EVM-5V-400K (not LM73606)?
Thank you very much!
Grace
Part Number: LM73606EVM-5V-400K Other Parts Discussed in Thread: LM73606 Tool/software: WEBENCH® Design Tools Hi,
I have bought the LM73606 EVM. and make a loss analysis report. Is there anything about loss analysis you can provide to me?
Thank you.
Dear Joe,
Thank you for your kind support.
first, they use boost converter to make 5V from 4.2V.
and I have more questions,
1. Can I adjust duty cycle changing the ratio of R1, R2 and R3? what would be happen If I use 400K,200K,400K or 4K,2K,4K instead…
Hey JH,
Please consider the 3.5% accuracy for each device regardless of lot or reel.
Here is the PSRR measurement for Vin=5.4V, Vout=5V, and Iout=1A:
To increase the PSRR performance for the 400k-600k range, the customer could place a feed forward capacitor…
Hi Robert,
Are you able to scopeshot the L5 inductor current? Place the current loop between L5 and the output capacitance.
If you cannot probe inductor current then the SW node voltage will be OK.
I think the device is hitting current limit, and it is…
Part Number: TPS63020
Tps63020 switching frequency is fixed 2.4m, my VIN range is 2.5-5, Vout = 3.3V, IOUT = 1a, the front with a DC / DC - switching frequency 1.2m output 5V, as the tps63020 input, found that tps63020 no output, the front DC / DC switch…
Hi Alfred:
Please see below with more data captured. Looks like the ripple changed proportional to Input Frequency.
I have tested with 100K-500KHz, Vcc2, Y, with and without Termination Jumper.
BK Precision 9130 Power Supply is set to 5V, Max Current…
Part Number: LM73605 Other Parts Discussed in Thread: LM76003 , LM73606EVM-5V-400K Hi, Could you tell me about LM73605 overcurrent and short-circuit protection? Now we're competing with LT8614. Customer is expecting a function of the following wording…
Hi Cedrick,
Thank you for the more detailed message. I think you may be using the device incorrectly or I may not be understanding your setup correctly. What I believe you're telling me is that you are lining a 400K resistor in series with the ADC input…
Hello Michael,
The unity gain bandwidth (UGB) is defined as 1MHz for all four gain settings, and it is measured using a 60pF load on the output (i.e. SOA). It is a very pessimistic specification, when in reality the amplifier has higher performance. You…
