3.1.4 Load Step Effects Across Output Channels

GUID-20230717-SS0I-X8XV-SHDH-1BQSLS8GQHX0-low.pngFigure 3-6 Load Step Effects Across Channels (AC Coupling)

The cross-channel load step test was performed using VIN = 12 V, and a load step from 48 Ω to 12 Ω on CH1. Voltage measurements for CH2-CH4 were made using AC coupling mode.
