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…
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 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…
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…
Part Number: LM73606 Hello,
My customer would like to know the ripple voltage of LM73606EVM.
[Condition]
1) Input voltage 12V, Output voltage 3.3V output current 6A
2) Input voltage 5V, Output voltage 3.3V output current 6A
We would like to know 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…
If anyone is facing an issue with this.
The following are the reasons for IC getting damaged.
1.) As the feedback pin is high impedance. If the divider circuit used is of the value above 400K. There are chances that during production testing or assembly…
Part Number: LMR33630 Tool/software: WEBENCH® Design Tools So I designed a 5V supply using LMR33630ADDR, switching frequency is 400kHz. We expect the input voltage would be as high as 36V, since that is what the chip is rated. In testing, the chip would…
