LV58132MX
Overview
LV58132MX is a 1ch step-down switching regulator. With built-in 0.25
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 90
μA at stand-by mode. It has over current protection for load devices. With external capacitor,
it achieves soft start.
