DESCRIPTION
The M4622 is a dual 2.5A step-down switching mode Power SoC(System on Chip)with integrated power MosFETs,inductor and input decoupling capacitor in BGA-25 package.The input voltage is from 4.5V to 18V.
The M4622 provides high efficiency with COT control mode for fast transient response and good loop stability.It works on FCCM which keeps low output ripple.
The M4622 indicates faults by PG and provides short circuit and over-load hiccup protection and over temperature shutdown protection.
APPLICATIONS
?Optical Module
?PoL Power Supply
?Solid-State and Hard Disk Drives
