n Side Wettable 40-Lead 6mm × 6mm QFN Package The LT®3383 is a complete power management solution
for advanced portable application processor-based systems. The device contains four synchronous step-down
DC/DC converters for core, memory, I/O, and system onchip (SoC) rails and three 300mA LDO regulators for low
noise analog supplies. APPLICATIONS A status pin is available to indicate regulator undervoltages.
If an overtemperature or low supply fault is detected all
regulators are disabled during the fault condition. n Regulator start-up is sequenced by connecting outputs to
enable pins in the desired order. A master power-on pin
is provided to initiate pin-strapped power-on sequences. Automotive
