POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
High current applications are described in table . The values are recommendations based on actual test circuits.
Many variations are possible based on the requirements of the user. Performance of teh circuit is dependent
upon the layout rather than the on specific components, if the device parameters are not exceeded. The power
stage, having the highest current levels and greatest dv/dt rates, should be given the most attention, as both
the supply and load can be severly affected by the power levels and edge rates.
