The switching converter's LX pin should have the following conditions for proper operation
In some no opto flyback applications this pin is tracked for output regulation, so care should be taken during…
The IC Datasheet is correct. The EP must be connected to SGND. There is a difference in the way the EP is connected in the MAX17682EVKITC. The short trace that connects EP to SGND pin 13 is missing in…
For the FB pin the requirement is to have a transformer designed with minimum leakage inductance and parasitics as possible. Isobuck operates by regulating the primary capacitor CPRI voltage (using primary…
As shown in the following figure, the MAX17682 has two internal N-MOS. The high side NMOS requires a higher gate voltage than the source to control the switch. To be able to turn the MOSFET fully on, the…
The reason for size difference is due to the usage of the minimum pad size Exposed Pad on the Land pattern to maintain at least 0.20mm between lead pad and thermal pad (to avoid shorting).
