9.1.1 Parallel Configuration

To increase current capabilities and to lower RON, both channels can be placed in parallel as seen in Figure 9-1. With this configuration, the CT1 and CT2 pins can be tied together to use one capacitor, CT.

See the TPS22966 Dual-Channel Load Switch in Parallel Configuration application report and Parallel Load Switches for Higher Output Current & Reduced ON-Resistance Design Guide for more information.
