The package and Pin configuration of ADP1043A and ADP1046 are the same. What is key difference between ADP1043A and ADP1046A?
The ADP1046A is the updated version of ADP1043A. They are pin-to-pin compatible. The improvements of ADP1046A are:
Improved control loop with less noise
Fast OVP with analog comparator
Fast OCP with up to 440 timeout cycles
Pre-bias start up function
SR reverse current protection
Improved GO bit
Improved CS2 current sense accuracy
Output voltage slew rate control
Fast ORFET comparator improvements
Programmable smooth filter transitioning
Improved and more flexible Flag response
SR Turn off speed (3 new speed options)
Light Load mode hysteresis (programmable hysteresis)
Voltage Feed Forward
Programmable PGOOD1/2 functions
Improved Droop-sharing control
Improved constant current sharing function
Can I use the eval board of ADP1043A for ADP1046 devices?
currently adp1046eval board is not available with us and we need to verify a device failure encountered. we do only have the adp1043a eval board..would this be possible?
If you mean "will the ADP1046a daughter card work with ADP1043A power board" I believe the answer is yes. Please double check the pin outs of the daughter card in the user guide.
a clarification on my query. Can I use ADP1043A evalboard EVAL-ADP1043A Evaluation Board | Analog Devices in replacement for ADP1046A evalboard EVAL-ADP1046 Evaluation Board | Analog Devices ?
I believe they have same pin outs.,but does the components of each eval board the same?will it have no effect on the output that i would be gathering?
There have been some circuit modifications from 1043A to 1046A but it should be the same except for the OrFET polarity.
