LV5808MXZ Datasheet | SANYO

Ordering number : ENA1614 .. Bi-CMOS IC Overview Step-down Switching Regulator LV5808MXZ 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 MFP8 (200mil) employed. Current mode control type, with superior load current response and easy phase pensation 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: 370k Hz - Soft start - pact package: MFP8 (200mil) with heat sink 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 2.05 150 -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, P, SS pin maximum voltage Allowable power dissipation Junction temperature Operating temperature Storage temperature Note: Plan the maximum voltage while including coil and surge voltages, so that the maximum voltage is not exceeded even for an instant.
