LV5803NM
Overview
LV5803NM is a 1ch step-down switching regulator. 0.2
FET is incorporated on the upper side to achieve high-efficiency
operation for large output current. Low-heat resistance and compact-package MFP8 employed. Current mode control type,
with superior load current response and easy phase compensation ON/OFF pin, allowing the standby mode with the current
drain of 80
A 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
2A 1ch step-down switching regulator
Wide input dynamic range (4.5 to 18V)
