8 Parameter Measurement Information

GUID-20200903-CA0I-F7BM-XTCD-W5BJV7686ZFV-low.png
A. VIN is held constant during the test.
B. VRCP_ENTER is referenced from VOUT to VIN. It is the threshold that, when reached, will turn-off the main switch FETs to prevent reverse current flow.

A. VIN is held constant during the test.
B. VRCP_EXIT is referenced from VOUT to VIN. It is the threshold that, when reached, will turn-off the reverse current protection feature.
