LV5857MX
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 compensation 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.
