Description
General part information
LT3383 Series
The LT3383 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 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 undervoltages. If an overtemperature or low supply fault is detected all regulators are disabled during the fault condition.The device is available in a 40-lead 6mm × 6mm QFN with wettable flanks for optical inspection.APPLICATIONSAutomotiveIndustrialCommunicationsGeneral Purpose Multichannel Power Supplies
