LV5818M Datasheet | SANYO

.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 pact-package MFP12 employed. Current mode control type, with superior load current response and easy phase pensation 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. - Soft start - pact package: MFP12 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 1.65 150 -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, EN, P, SS, SYNC, RT pin maximum voltage Allowable power dissipation Junction temperature Operating temperature Storage temperature - Specified board: 46.4mm × 31.8mm ×1.7mm, glass epoxy both side. Note: Plan the maximum voltage while including coil and surge voltages, so that the maximum voltage is not exceeded even for an instant.
