LV5876MX
Step-down Switching Regulator
Overview
LV5876MX 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 μ A at stand-by mode. It has cycle-by-cycle over current protection for load devices. With
external capacitor, it achieves soft start.
Functions
? 2.0A 1ch step-down regulator
? Small package: MFP8 (200mil) with heat sink
? High efficiency (88% IOUT = 1A, VIN = 12V, VO = 5V)
? Standby mode
? Over-current protection
Specifications
