LV5818M

www.DataSheet.co.kr Ordering number : ENA1900 Bi-CMOS IC LV5818M Overview Step-down Switching Regulator LV5818M is a 1ch step-down switching regulator. 0.3Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current. Low-heat resistance and compact-package MFP12 employed. Current mode control type, with superior load current response and easy phase compensation EN pin, allowing the standby mode with the current drain of 70μA 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 ( to 28V) High efficiency (90% IOUT = 1A, VIN = 12V, VO = 5V) Standby mode Over-current protection External synchronous driving Thermal shutdown Reference voltage: 0.8V The frequency is changeable in external resistance.
