LV5856MX
Step-down Switching Regulator
Overview
LV5856MX is a 1ch step-down switching regulator. With built-in two 0.13
Ω 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 compensation is easy. With ON/OFF pin,
operating can be less than 60
μA at stand-by mode. It has cycle-by-cycle over current protection for load devices. With
external capacitor, it achieves soft start.
