APPLICATION INFORMATION
connections
Connections from the drivers to the gate of the power MOSFETs should be as short and wide as
possible to reduce stray inductance. This becomes more critical if external gate resistors are not being
used. In addition, as for the current limit noise issue, use of a gate resistor on the high-side MOSFET(s)
considerably reduce the noise at the LL node, improving the performance of the current limit function.
The connection from LL to the power MOSFETs should be as short and wide as possible.
