LT3383 Multi-Output Power Management Solution

Analog Devices LT3383 Multi-Output Power Management Solution is for advanced portable application processor-based systems. The device contains four synchronous step-down DC/DC converters for core, memory, I/O, and system-on-chip (SoC) rails and three 300mA LDO regulators for low noise analog supplies. 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. A status pin is available to indicate regulator under voltages. If an over temperature or low supply fault is detected, all regulators are disabled during the fault condition. The Analog Devices LT3383 is available in a 40-lead 6mm × 6mm QFN with wettable flanks for optical inspection.
