Hi, NXP.....

ask for MC34844.


We found to update your datasheet, that is add resistor from VDC1 to VDC3.
ask to this point.
1. if don't apply what happens if we don't apply this resistor.
2. Reason to add this resistor.


About circuit.
1. if add resistor(about 10ohm) to pin#10~pin#19 (LED feedback line) what happens.
2. What is the difference between MC34844EP and MC34844AEP?
