LM73605: L/S MOS current limit spec

Tiger Yeh

Part Number: LM73605

Hi,

LM73605 is 5A buck converter, may I know why its minimum threshold of low-side current limit is 4.79A that is less than 5A?

Best regard,

Tiger

Sorry, I found the answer from datasheet note.
Please discard this question.
============================================================================
(2) This current limit was measured as the internal comparator trip point. Due to inherent delays in the current limit comparator and drivers,
the peak current limit measured in closed loop with faster slew rate will be larger, and valley current limit will be lower.
