Bi-CMOS IC
Overview
Step-down Switching Regulator
LV5857MX is a 1ch step-down switching regulator. With built-in two 0.13Ω power MOSFET switch, it achieves high output current and high efficiency. With low-heat resistance, miniature package MFP8 (200mil) with heat-sink is adopted. Since it is Current mode control type, it has good load current response, and phase pensation is easy. With ON/OFF pin, operating can be less than 60μA at stand-by mode. It has cycle-by-cycle over current protection for load devices. With external capacitor, it achieves soft start.
