LV5806MX

Ordering number : ENA1513 www.DataSheet4U.com Bi-CMOS IC LV5806MX Overview Step-down Switching Regulator LV5806MX is a 1ch step-down switching regulator. 0.13Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current. Low-heat resistance and compact-package MFP8 (with Heat sink) 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 100μA 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 3A 1ch step-down switching regulator Wide input dynamic range (to 28V) High efficiency : 90% (IOUT = 1A, VIN = 12V, VO = 5V) Standby mode Over-current protection Thermal shutdown Reference voltage : 0.8V Fixed frequency : 370kHz Soft start Compact package : MFP8 (200mil) with Heat sink Applications LCD TV.
