LV5858M
Overview
Step-down Switching Regulator
LV5858M is a 3A and 1ch step-down switching regulator. 0.1Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current. Current mode control type, with superior load current response and easy phase pensation ON/OFF pin, allowing the standby mode with the current drain of 60μA or less Pulse-by-pulse over-current protection and overheat protection available for protection of load devices Soft start pin to be provided with a capacitance for soft start.
Functions
