LA5724M - Monolithic Linear IC Separately-Excited Step-Down Switching Regulator

Description

1.

Overcurrent protection function The overcurrent protection function detects, on a cycle-by-cycle basis, the output transistor current and turns off that output transistor current if it exceeds 0.7A in a cycle-by-cycle manner.
