LV5807MX

Ordering number : ENA1495A www.DataSheet4U.com Bi-CMOS IC LV5807MX Overview Step-down Switching Regulator LV5807MX is a 1ch step-down switching regulator. 0.12Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current. Low-heat resistance and compact-package MFP8 (200mil) 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 40μA 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 3A 1ch step-down switching regulator Wide input dynamic range (8 to 18V) High efficiency (90% IOUT = 1A, VIN = 12V, VO = 5V) Standby mode Over-current protection Thermal shutdown Reference voltage: 0.79V Fixed frequency: 385kHz Soft start Compact package: MFP8 (200mil) with Exposed Pad Specifications Parameter Maximum Ratings at Ta = 25°C Symbol VIN max VBT max VSW max VBS-SW max VEN max Vfs max Pd max Tj max Topr Tstg Mount on a specified board * Conditions Ratings 20 25 VIN max 7 20 7 2.05 150 -20 to 80 -40 to 150 Unit V V V V V V W °C °C °C Maximum input VIN voltage BOOT pin maximum voltage SW pin maximum voltage BOOT pin-SW pin maximum voltage EN pin maximum voltage FB, COMP, SS pin maximum voltage Allowable power dissipation Junction temperature Operating temperature Storage temper...
