LV58761MX
Overview
LV58761MX 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 MFP8J (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.
Functions
1.5A 1ch step-down regulator
Small package: MFP8J (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)
