Description

The functionality of existing load switches can be expanded by placing multiple channels in a parallel configuration.  This TID demonstrates two examples of paralleling load switches.
The first uses both channels of the dual channel TPS22966 for a total output current of 10A.
The second uses three TPS22959 in parallel for a total output current of 30A.

Features
  • Increased Maximum Output Current
  • Reduced Total ON-Resistance (RON)
  • Faster Output Rise Time
  • Lower Power Dissipation
  • Reduced Quick Output Discharge  (QOD) Resistance
