Description
General part information
LT3380 Series
The LT3380 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. An I2C serial port may be used to control regulator enables, power-down sequencing, output voltage levels, dynamic voltage scaling, operating modes, and status reporting.Regulator start-up is sequenced by connecting outputs to enable pins in the desired order or via the I2C port. The LT3380 outputs may be sequenced off in one of four time slots selected using I2C command registers.The device is available in a 40-lead 6mm × 6mm QFN with wettable flanks for optical inspection.APPLICATIONSAutomotiveIndustrialCommunicationsGeneral Purpose Multichannel Power Supplies
