thank you for your reply actually I would like to measure load current in a dc-dc buck converter.
sequence is
buck output --Rsense 20m ohm ---load 6 ohm---gnd
hi, I would like to sense the current from a path where a current of 50mA to 2 A is flowing to the load. Can I use simple differential amp with gain across the Rsense =20mohm or is there any contemporary design help.
thanks
u can buy with cheaper price , I think just check your output voltage matches with your tablet.. but higher current is no problem.. you device will draw the current as required.
hi , I designed conventional single inductor two output dc-dc boost converter in psim. means inductor energy is stored and thrown to 1 output at one cycle and charged and discharged to the 2nd output at next cycle. the two outputs are sensed by using voltage dividers and time multiplexed using...
in the low power boost converter I am changing the load from 40mA to 60mA ,
fluctuation becomes different for each different feedback resistances. what is reason behind this ?
thanks
thanks . but should we run the loop equal or greater than switching freq.
if fs =4MHz,, what could be bandwidth.
BW < fs or , BW > fs
in case of digital control
Hi,
I designed simple structure of dc-dc step up synchronous converter with digital control. means output voltage is converted to digital using A/D converter then fed to digital filter and then duty generation accomplished.
dc-dc is working fine but my question is how to calculate sample time...
hi,
in case of dc-dc converters what is the main difference between switching freq , bandwidth and cross over frequency.
is the cross over frequency is almost equal to bandwidth ?
thanks
Hi,
I have configured simple dc-dc step-up converter using smart control. after every thing is configured i select to export the regulator way to “s-domain Co-efficient”. when it is successfully exported we can see two summations and controller transfer function block. my question is why the...
in case of boost converter what I think is IL average is equal to input current. please correct me if I am wrong thanks . please see the attached diagram
