LV5810M

www.DataSheet.co.kr Ordering number : ENA1558 Bi-CMOS IC LV5810M Overview Step-down Switching Regulator LV5810M 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 (225mil) 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 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 Thermal shutdown Reference voltage: 0.8V Fixed frequency: 370kHz Soft start Compact package: MFP8 (225mil) Specifications Parameter Maximum Ratings at Ta = 25°C Symbol VIN max VBT max VSW max VBS-SW max Vfs max Pd max Tj max Topr Tstg Mount on a specified board * Conditions Ratings 32 37 VIN max 7 7 1.15 150 -20 to 80 -40 to 150 Unit 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 FB, COMP, SS pin maximum voltage Allowable power dissipation Junction temperature Operating temperature Storage temperature * Specified board: 46.4mm × 31.8mm ×1.7mm, glass ...
