Overview
Step-down Switching
Regulator
LV5876MX is a 1ch step-down switching
regulator. With built-in 0.25Ω 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 90μA 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
Thermal shutdown protection Reference voltage: 0.8V Inside frequency: 950kHz Soft start Wide input dynamic range (4.75 to 18V)
